Set IORESOURCE_SYSTEM_RAM in flags of resource ranges with
"System RAM", "Kernel code", "Kernel data", and "Kernel bss".
Note that:
- IORESOURCE_SYSRAM (i.e. modifier bit) is set in flags when
IORESOURCE_MEM is already set. IORESOURCE_SYSTEM_RAM is defined
as (IORESOURCE_MEM|IORESOURCE_SYSRAM).
- Some archs do not set 'flags' for children nodes, such as
"Kernel code". This patch does not change 'flags' in this
case.

The interrupt-parent property is not needed as it is inherited from
the parent bus and in the case of the CAAM node actively points to
the wrong interrupt controller (GIC instead of GPC). This leads to
the CAAM IRQs not getting unmasked at the GPC level, leaving them
unable to wake the CPU from wait mode, potentially impacting
performance of the CAAM unit when CPUidle is enabled.

now use DEBUG_RODATA. Let's enable ARM_KERNMEM_PERMS so that

And while testing things on various devices, I noticed we're
missing few loadable modules to make things more usable:
- USB Ethernet for smsc75xx, we only have smsc97xx right now
- Basic USB serial drivers for things like ftdi and pl2303 ports

We don't want to write to .text section. Let's move l2dis_3630
to .data and access it via a pointer.
For calculating the offset, let's optimize out the add and do it
in ldr/str as suggested by Nicolas Pitre <nicolas.pitre@linaro.org>.

We don't want to be writing to .text so it can be set rodata.
Fix error "Unable to handle kernel paging request at virtual address
c012396c" in wait_dll_lock_timed if CONFIG_DEBUG_RODATA is selected.
As these counters are for debugging only and unused, we can just

The legacy-style mailbox device creation is supported currently
only for OMAP3, as all other SoCs are DT-boot only. Even on this
SoC, there are no client drivers that utilize these mailbox devices.
So, clean up the legacy-style mailbox device instantiation logic.
The mailbox devices are already present and supported for the DT
boot on OMAP3.

Add ti,mbox-send-noirq to wkup_m3 mailbox so that messages using

This is required to be able to send multiple messages to the WkupM3

need to add something to the build and doesn't work if obj-y

Pull more power management and ACPI updates from Rafael Wysocki:
"This includes fixes on top of the previous batch of PM+ACPI updates
and some new material as well.
From the new material perspective the most significant are the driver
core changes that should allow USB devices to stay suspended over
system suspend/resume cycles if they have been runtime-suspended
already beforehand. Apart from that, ACPICA is updated to upstream
revision 20160108 (cosmetic mostly, but including one fixup on top of
the previous ACPICA update) and there are some devfreq updates the
didn't make it before (due to timing).
A few recent regressions are fixed, most importantly in the cpuidle
menu governor and in the ACPI backlight driver and some x86 platform
drivers depending on it.
Some more bugs are fixed and cleanups are made on top of that.

As usual, a bunch of commits, mostly adding drivers and other options to
defconfigs because it makes sense to have them enabled on various development

There's an introduction of a pxa_defconfig, since PXA finally will allow
building a shared kernel for all boards. With this, we can hopefully
remove a bunch of individual defconfigs down the road but it requires
a bit of real life testing and transition period.

This branch is the culmination of 5 years of effort to bring the ARMv6
and ARMv7 platforms together such that they can all be enabled and
boot the same kernel. It has been a tremendous amount of cleanup and
refactoring by a huge number of people, and creation of several new
(and major) subsystems to better abstract out all the platform details
in an appropriate manner.
The bulk of this branch is a large patchset from Arnd that brings several
of the more minor and older platforms we have closer to multiplatform
support. Among these are MMP, S3C64xx, Orion5x, mv78xx0 and realview
Much of this is moving around header files from old mach directories,
but there are also some cleanup patches of debug_ll (lowlevel debug
per-platform options) and other parts.
Linus Walleij also has some patchs to clean up the older ARM Realview
platforms by finally introducing DT support, and Rob Herring has some
for ARM Versatile which is now DT-only. Both of these platforms are
now multiplatform.
Finally, a couple of patches from Russell for Dove PMU, and a fix from
Valentin Rothberg for Exynos ADC, which were rebased on top of the
series to avoid conflicts.

Merge tag 'armsoc-multiplatform' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC multiplatform code updates from Arnd Bergmann:
"This branch is the culmination of 5 years of effort to bring the ARMv6
and ARMv7 platforms together such that they can all be enabled and
boot the same kernel. It has been a tremendous amount of cleanup and
refactoring by a huge number of people, and creation of several new
(and major) subsystems to better abstract out all the platform details
in an appropriate manner.
The bulk of this branch is a large patchset from Arnd that brings
several of the more minor and older platforms we have closer to
multiplatform support. Among these are MMP, S3C64xx, Orion5x, mv78xx0
and realview Much of this is moving around header files from old mach
directories, but there are also some cleanup patches of debug_ll
(lowlevel debug per-platform options) and other parts.
Linus Walleij also has some patchs to clean up the older ARM Realview
platforms by finally introducing DT support, and Rob Herring has some
for ARM Versatile which is now DT-only. Both of these platforms are
now multiplatform.
Finally, a couple of patches from Russell for Dove PMU, and a fix from
Valentin Rothberg for Exynos ADC, which were rebased on top of the
series to avoid conflicts"

During my randconfig build testing, I found that a kernel with
DEBUG_AT91_UART and ARCH_BCM_63XX fails to build:
arch/arm/include/debug/at91.S:18:0: error: "CONFIG_DEBUG_UART_VIRT" redefined [-Werror]
It turns out that the DEBUG_UART_BCM63XX option is enabled whenever
the ARCH_BCM_63XX is, and that breaks multiplatform kernels because
we then end up using the UART address from BCM63XX rather than the
one we actually configured (if any).
This changes the BCM63XX options to only have one Kconfig option,
and only enable that if the user explicitly turns it on.

Infrastructural changes:
- In struct gpio_chip, rename the .dev node to .parent to better reflect
the fact that this is not the GPIO struct device abstraction. We will
add that soon so this would be totallt confusing.
- It was noted that the driver .get_value() callbacks was
sometimes reporting negative -ERR values to the gpiolib core, expecting
them to be propagated to consumer gpiod_get_value() and gpio_get_value()
calls. This was not happening, so as there was a mess of drivers
returning negative errors and some returning "anything else than zero"
to indicate that a line was active. As some would have bit 31 set to
indicate "line active" it clashed with negative error codes. This is
fixed by the largeish series clamping values in all drivers with
!!value to [0,1] and then augmenting the code to propagate error codes
to consumers. (Includes some ACKed patches in other subsystems.)
- Add a void *data pointer to struct gpio_chip. The container_of() design
pattern is indeed very nice, but we want to reform the struct gpio_chip
to be a non-volative, stateless business, and keep states internal to
the gpiolib to be able to hold on to the state when adding a proper
userspace ABI (character device) further down the road. To achieve this,
drivers need a handle at the internal state that is not dependent on
their struct gpio_chip() so we add gpiochip_add_data() and
gpiochip_get_data() following the pattern of many other subsystems.
All the "use gpiochip data pointer" patches transforms drivers to this
scheme.
- The Generic GPIO chip header has been merged into the general
<linux/gpio/driver.h> header, and the custom header for that removed.
Instead of having a separate mm_gpio_chip struct for these generic
drivers, merge that into struct gpio_chip, simplifying the code and
removing the need for separate and confusing includes.
Misc improvements:
- Stabilize the way GPIOs are looked up from the ACPI legacy
specification.
- Incremental driver features for PXA, PCA953X, Lantiq (patches from the
OpenWRT community), RCAR, Zynq, PL061, 104-idi-48
New drivers:
- Add a GPIO chip to the ALSA SoC AC97 driver.

Merge tag 'gpio-v4.5-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio
Pull GPIO updates from Linus Walleij:
"Here is the bulk of GPIO changes for v4.5.
Notably there are big refactorings mostly by myself, aimed at getting
the gpio_chip into a shape that makes me believe I can proceed to
preserve state for a proper userspace ABI (character device) that has
already been proposed once, but resulted in the feedback that I need
to go back and restructure stuff. So I've been restructuring stuff.
On the way I ran into brokenness (return code from the get_value()
callback) and had to fix it. Also, refactored generic GPIO to be
simpler.
Some of that is still waiting to trickle down from the subsystems all
over the kernel that provide random gpio_chips, I've touched every
single GPIO driver in the kernel now, oh man I didn't know I was
responsible for so much...
Apart from that we're churning along as usual.
I took some effort to test and retest so it should merge nicely and we
shook out a couple of bugs in -next.
Infrastructural changes:
- In struct gpio_chip, rename the .dev node to .parent to better
reflect the fact that this is not the GPIO struct device
abstraction. We will add that soon so this would be totallt
confusing.
- It was noted that the driver .get_value() callbacks was sometimes
reporting negative -ERR values to the gpiolib core, expecting them
to be propagated to consumer gpiod_get_value() and gpio_get_value()
calls. This was not happening, so as there was a mess of drivers
returning negative errors and some returning "anything else than
zero" to indicate that a line was active. As some would have bit
31 set to indicate "line active" it clashed with negative error
codes. This is fixed by the largeish series clamping values in all
drivers with !!value to [0,1] and then augmenting the code to
propagate error codes to consumers. (Includes some ACKed patches
in other subsystems.)
- Add a void *data pointer to struct gpio_chip. The container_of()
design pattern is indeed very nice, but we want to reform the
struct gpio_chip to be a non-volative, stateless business, and keep
states internal to the gpiolib to be able to hold on to the state
when adding a proper userspace ABI (character device) further down
the road. To achieve this, drivers need a handle at the internal
state that is not dependent on their struct gpio_chip() so we add
gpiochip_add_data() and gpiochip_get_data() following the pattern
of many other subsystems. All the "use gpiochip data pointer"
patches transforms drivers to this scheme.
- The Generic GPIO chip header has been merged into the general
<linux/gpio/driver.h> header, and the custom header for that
removed. Instead of having a separate mm_gpio_chip struct for
these generic drivers, merge that into struct gpio_chip,
simplifying the code and removing the need for separate and
confusing includes.
Misc improvements:
- Stabilize the way GPIOs are looked up from the ACPI legacy
specification.
- Incremental driver features for PXA, PCA953X, Lantiq (patches from
the OpenWRT community), RCAR, Zynq, PL061, 104-idi-48
New drivers:
- Add a GPIO chip to the ALSA SoC AC97 driver.
- Add a new Broadcom NSP SoC driver (this lands in the pinctrl dir,
but the branch is merged here too to account for infrastructural
changes).
- The sx150x driver now supports the sx1502"

We've had quite busy weeks in this cycle. Looking at ALSA core, the
significant changes are a few fixes wrt timer and sequencer ioctls
that have been revealed by fuzzer recently. Other than that, ASoC
core got a few updates about DAI link handling, but these are rather
straightforward refactoring.
In drivers scene, ASoC received quite lots of new drivers in addition
to bunch of updates for still ongoing Intel Skylake support and
topology API. HD-audio gained a new HDMI/DP hotplug notification via
component. FireWire got a pile of code refactoring/updates with
SCS.1x driver integration.
More highlights are shown below.
[NOTE: this contains also many commits for DRM. This is due to the
pull of drm stable branch into sound tree, as the base of i915 audio
component work for HD-audio. The highlights below don't contain
these DRM changes, as these are supposed to be pulled via drm tree in
anyway sooner or later.]
Core
- Handful fixes to harden ALSA timer and sequencer ioctls against
races reported by syzkaller fuzzer
- Irq description string can be unique to each card; only for
HD-audio for now
ASoC
- Conversion of the array of DAI links to a list for supporting
dynamically adding and removing DAI links
- Topology API enhancements to make everything more component based
and being able to specify PCM links via topology
- Some more fixes for the topology code, though it is still not final
and ready for enabling in production; we really need to get to the
point where that can be done
- A pile of changes for Intel SkyLake drivers which hopefully deliver
some useful initial functionality for systems with this chipset,
though there is more work still to come

As illustrated by commit a3afe70b83 ("[S390] latencytop s390
support."), HAVE_LATENCYTOP_SUPPORT is defined by an architecture to
advertise an implementation of save_stack_trace_tsk.
However, as of 9212ddb5ea ("stacktrace: provide save_stack_trace_tsk()
weak alias") a dummy implementation is provided if STACKTRACE=y. Given
that LATENCYTOP already depends on STACKTRACE_SUPPORT and selects
STACKTRACE, we can remove HAVE_LATENCYTOP_SUPPORT altogether.

To date, we have implemented two I/O usage models for persistent memory,
PMEM (a persistent "ram disk") and DAX (mmap persistent memory into
userspace). This series adds a third, DAX-GUP, that allows DAX mappings
to be the target of direct-i/o. It allows userspace to coordinate
DMA/RDMA from/to persistent memory.
The implementation leverages the ZONE_DEVICE mm-zone that went into
4.3-rc1 (also discussed at kernel summit) to flag pages that are owned
and dynamically mapped by a device driver. The pmem driver, after
mapping a persistent memory range into the system memmap via
devm_memremap_pages(), arranges for DAX to distinguish pfn-only versus
page-backed pmem-pfns via flags in the new pfn_t type.
The DAX code, upon seeing a PFN_DEV+PFN_MAP flagged pfn, flags the
resulting pte(s) inserted into the process page tables with a new
_PAGE_DEVMAP flag. Later, when get_user_pages() is walking ptes it keys
off _PAGE_DEVMAP to pin the device hosting the page range active.
Finally, get_page() and put_page() are modified to take references
against the device driver established page mapping.
Finally, this need for "struct page" for persistent memory requires
memory capacity to store the memmap array. Given the memmap array for a
large pool of persistent may exhaust available DRAM introduce a
mechanism to allocate the memmap from persistent memory. The new
"struct vmem_altmap *" parameter to devm_memremap_pages() enables
arch_add_memory() to use reserved pmem capacity rather than the page
allocator.
This patch (of 18):
The core has developed a need for a "pfn_t" type [1]. Move the existing
pfn_t in KVM to kvm_pfn_t [2].

Let's define page_mapped() to be true for compound pages if any
sub-pages of the compound page is mapped (with PMD or PTE).
On other hand page_mapcount() return mapcount for this particular small
page.
This will make cases like page_get_anon_vma() behave correctly once we
allow huge pages to be mapped with PTE.
Most users outside core-mm should use page_mapcount() instead of
page_mapped().

Merge first patch-bomb from Andrew Morton:
- A few hotfixes which missed 4.4 becasue I was asleep. cc'ed to
-stable
- A few misc fixes
- OCFS2 updates
- Part of MM. Including pretty large changes to page-flags handling
and to thp management which have been buffered up for 2-3 cycles now.
I have a lot of MM material this time.
[ It turns out the THP part wasn't quite ready, so that got dropped from
this series - Linus ]

zsmalloc: reorganize struct size_class to pack 4 bytes hole
mm/zbud.c: use list_last_entry() instead of list_tail_entry()
zram/zcomp: do not zero out zcomp private pages
zram: pass gfp from zcomp frontend to backend

drivers/base/memory.c: fix kernel warning during memory hotplug on ppc64
mm/page_isolation: use macro to judge the alignment
mm: fix noisy sparse warning in LIBCFS_ALLOC_PRE()
mm: rework virtual memory accounting
include/linux/memblock.h: fix ordering of 'flags' argument in comments

memory-hotplug: don't BUG() in register_memory_resource()
hugetlb: make mm and fs code explicitly non-modular
mm/swapfile.c: use list_for_each_entry_safe in free_swap_count_continuations

mm: make sure isolate_lru_page() is never called for tail page
vmstat: make vmstat_updater deferrable again and shut down on idle
...
CONFIG_DEBUG_INFO_SPLIT will split debug info on
.dwo files. This will generate a smaller vmlinux and
smaller .ko modules, which will be easier to ship on
certain products.
CONFIG_DEBUG_INFO_DWARF4 will generate debug info in
DWARF4 format, which ends up being larger, but
improves the probability of resolving variables in
optmized code.

Pull livepatching updates from Jiri Kosina:
- RO/NX attribute fixes for patch module relocations from Josh
Poimboeuf. As part of this effort, module.c has been cleaned up as
well and livepatching is piggy-backing on this cleanup. Rusty is OK
with this whole lot going through livepatching tree.

also
Reviewed-by: Miroslav Benes <mbenes@suse.cz>
but this came in only after I've alredy pushed out. Didn't want to
rebase because of that, hence I am mentioning it here.
- symbol lookup fix from Miroslav Benes
* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jikos/livepatching:
livepatch: Cleanup module page permission changes
module: keep percpu symbols in module's symtab

module: use a structure to encapsulate layout.
gcov: use within_module() helper.
module: Use the same logic for setting and unsetting RO/NX
livepatch: function,sympos scheme in livepatch sysfs directory
livepatch: add sympos as disambiguator field to klp_reloc
livepatch: add old_sympos as disambiguator field to klp_func
arm: arch_mmap_rnd() uses a hard-code value of 8 to generate the random
offset for the mmap base address. This value represents a compromise
between increased ASLR effectiveness and avoiding address-space
fragmentation. Replace it with a Kconfig option, which is sensibly
bounded, so that platform developers may choose where to place this
compromise. Keep 8 as the minimum acceptable value.

1/ Media error handling: The 'badblocks' implementation that originated
in md-raid is up-levelled to a generic capability of a block device.
This initial implementation is limited to being consulted in the pmem
block-i/o path. Later, 'badblocks' will be consulted when creating
dax mappings.
2/ Raw block device dax: For virtualization and other cases that want
large contiguous mappings of persistent memory, add the capability to
dax-mmap a block device directly.
3/ Increased /dev/mem restrictions: Add an option to treat all io-memory
as IORESOURCE_EXCLUSIVE, i.e. disable /dev/mem access while a driver is
actively using an address range. This behavior is controlled via the
new CONFIG_IO_STRICT_DEVMEM option and can be overridden by the
existing "iomem=relaxed" kernel command line option.
4/ Miscellaneous fixes include a 'pfn'-device huge page alignment fix,
block device shutdown crash fix, and other small libnvdimm fixes.

Merge tag 'libnvdimm-for-4.5' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm
Pull libnvdimm updates from Dan Williams:
"The bulk of this has appeared in -next and independently received a
build success notification from the kbuild robot. The 'for-4.5/block-
dax' topic branch was rebased over the weekend to drop the "block
device end-of-life" rework that Al would like to see re-implemented
with a notifier, and to address bug reports against the badblocks
integration.
There is pending feedback against "libnvdimm: Add a poison list and
export badblocks" received last week. Linda identified some localized
fixups that we will handle incrementally.

Generic MTD
* populate the MTD device 'of_node' field (and get a proper 'of_node' symlink
in sysfs)
- This yielded some new helper functions, and changes across a variety of
drivers
* partitioning cleanups, to prepare for better device-tree based partitioning
in the future
- Eliminate a lot of boilerplate for drivers that want to use OF-based
partition parsing
- The DT bindings for this didn't settle yet, so most non-cleanup portions
are deferred for a future release
NAND
* embed a struct mtd_info inside struct nand_chip
- This is really long overdue; too many drivers have to do the same silly
boilerplate to allocate and link up two "independent" structs, when in
fact, everyone is assuming there is an exact 1:1 relationship between a
NAND chips struct and its underlying MTD. This aids improved helpers and
should make certain abstractions easier in the future.
- Also causes a lot of churn, helped along by some automated code
transformations
* add more core support for detecting (and "correcting") bitflips in erased
pages; requires opt-in by drivers, but at least we kill a few bad
implementations and hopefully stave off future ones
* pxa3xx_nand: cleanups, a few fixes, and PM improvements
* new JZ4780 NAND driver
SPI NOR
* provide default erase function, for controllers that just want to send the
SECTOR_ERASE command directly
* fix some module auto-loading issues with device tree ("jedec,spi-nor")
* error handling fixes
* new Mediatek QSPI flash driver
Other
* cfi: force valid geometry Kconfig (finally!)
- this one used to trip up randconfigs occasionally, since bots aren't
deterred by big scary "advanced configuration" menus
More? Probably. See the commit logs.

- Add a debugfs-based interface for interacting with the ACPICA's
AML debugger introduced in the previous cycle and a new user
space tool for that, fix some bugs related to the AML debugger
and clean up the code in question (Lv Zheng, Dan Carpenter,
Colin Ian King, Markus Elfring).
- Update ACPICA to upstream revision 20151218 including a number
of fixes and cleanups in the ACPICA core (Bob Moore, Lv Zheng,
Labbe Corentin, Prarit Bhargava, Colin Ian King, David E Box,
Rafael Wysocki).
In particular, the previously added erroneous support for the
_SUB object is dropped, the concatenate operator will support
all ACPI objects now, the Debug Object handling is improved,
the SuperName handling of parameters being control methods is
fixed, the ObjectType operator handling is updated to follow
ACPI 5.0A and the handling of CondRefOf and RefOf is updated
accordingly, module-level code will be executed after loading
each ACPI table now (instead of being run once after all tables
containing AML have been loaded), the Operation Region handlers
management is updated to fix some reported problems and a the
ACPICA code in the kernel is more in line with the upstream
now.
- Update the ACPI backlight driver to provide information on
whether or not it will generate key-presses for brightness
change hotkeys and update some platform drivers (dell-wmi,
thinkpad_acpi) to use that information to avoid sending double
key-events to users pace for these, add new ACPI backlight
quirks (Hans de Goede, Aaron Lu, Adrien Schildknecht).
- Improve the ACPI handling of interrupt GPIOs (Christophe Ricard).

Pull oower management and ACPI updates from Rafael Wysocki:
"As far as the number of commits goes, ACPICA takes the lead this time,
followed by cpufreq and the device properties framework changes.
The most significant new feature is the debugfs-based interface to the
ACPICA's AML debugger added in the previous cycle and a new user space
tool for accessing it.
On the cpufreq front, the core is updated to handle governors more
efficiently, particularly on systems where a single cpufreq policy
object is shared between multiple CPUs, and there are quite a few
changes in drivers (intel_pstate, cpufreq-dt etc).
The device properties framework is updated to handle built-in (ie
included in the kernel itself) device properties better, among other
things by adding a fallback mechanism that will allow drivers to
provide default properties to be used in case the plaform firmware
doesn't provide the properties expected by them.
The Operating Performance Points (OPP) framework gets new DT bindings
and debugfs support.
A new cpufreq driver for ST platforms is added and the ACPI driver for
AMD SoCs will now support the APM X-Gene ACPI I2C device.
The rest is mostly fixes and cleanups all over.
Specifics:
- Add a debugfs-based interface for interacting with the ACPICA's AML
debugger introduced in the previous cycle and a new user space tool
for that, fix some bugs related to the AML debugger and clean up
the code in question (Lv Zheng, Dan Carpenter, Colin Ian King,
Markus Elfring).
- Update ACPICA to upstream revision 20151218 including a number of
fixes and cleanups in the ACPICA core (Bob Moore, Lv Zheng, Labbe
Corentin, Prarit Bhargava, Colin Ian King, David E Box, Rafael
Wysocki).
In particular, the previously added erroneous support for the _SUB
object is dropped, the concatenate operator will support all ACPI
objects now, the Debug Object handling is improved, the SuperName
handling of parameters being control methods is fixed, the
ObjectType operator handling is updated to follow ACPI 5.0A and the
handling of CondRefOf and RefOf is updated accordingly, module-
level code will be executed after loading each ACPI table now
(instead of being run once after all tables containing AML have
been loaded), the Operation Region handlers management is updated
to fix some reported problems and a the ACPICA code in the kernel
is more in line with the upstream now.
- Update the ACPI backlight driver to provide information on whether
or not it will generate key-presses for brightness change hotkeys
and update some platform drivers (dell-wmi, thinkpad_acpi) to use
that information to avoid sending double key-events to users pace
for these, add new ACPI backlight quirks (Hans de Goede, Aaron Lu,
Adrien Schildknecht).
- Improve the ACPI handling of interrupt GPIOs (Christophe Ricard).
- Fix the handling of the list of device IDs of device objects found
in the ACPI namespace and add a helper for checking if there is a
device object for a given device ID (Lukas Wunner).
- Change the logic in the ACPI namespace scanning code to create
struct acpi_device objects for all ACPI device objects found in the

"In the past, I have funnelled perf updates through the respective
architecture trees, but now that the arm/arm64 perf driver has been
largely consolidated under drivers/perf/, it makes more sense to send
a separate pull, particularly as I'm listed as maintainer for all the
files involved. I offered the branch to arm-soc, but Arnd suggested
that I just send it to you directly.
So, here is the arm/arm64 perf queue for 4.5. The main features are
described below, but the most useful change is from Drew, which
advertises our architected event mapping in sysfs so that the perf
tool is a lot more user friendly and no longer requires the use of
magic hex constants for profiling common events.

posix-clock: Fix return code on the poll method's error path
The palmas PMIC has two control lines that need to be muxed properly
for things to work. The sys_nirq pin is used for interrupts, and msecure
pin is used for enabling writes to some PMIC registers.
Without these pins configured properly things can fail in mysterious
ways. For example, we can't update the RTC registers on palmas PMIC
unless the msecure pin is configured. And this is probably the reason
why we had RTC missing from the omap5 dts file.
According to "OMAP5430 ES2.0 Data Manual [Public] VErsion A (Rev. F)"
swps052f.pdf, mux mode 1 is for sys_drm_msecure so in theory there's
should be no need to configure it as a GPIO pin.
However, it seems there are some reliability issues using the msecure
mux mode. And the TI trees configure the msecure pin as GPIO out high
instead.
As the PMIC only cares that the msecure line is high to allow access
to the RTC registers, let's use a GPIO hog as suggested by Nishanth
Menon <nm@ti.com>. Also the use of the internal pull was considered
but supposedly that may not be capable of keeping the line high in
a noisy environment.
If we ever see high security omap5 products in the mainline tree,
those need to skip the msecure pin muxing and ignore setting the GPIO
hog. Chances are the related pin mux registers are locked in that case
and the msecure pin is managed by whatever software may be running in
the ARM TrustZone.
Who knows what the original intention of the msecure pin was. Maybe
it was supposed to prevent the system time to be set back for some
game demo modes to time out? Anyways, it seems that later PMICs like
tps659037 have recycled this pin for "powerhold" and devices like
beagle-x15 do not need changes to the msecure pin configuration.
To avoid further confusion with TWL variant PMICs, beagle-x15 does
not have a back-up battery for RTC palmas. Instead the mcp79410 RTC
is used with rtc-ds1307 driver. There is a "powerhold" jumper j5
holes near the palmas PMIC, and shorting it seems to power up
beagle-x15 automatically. It is unknown if it also has other side
effects to the beagle-x15 power up sequence.

Looks like we have a GPMC bus timing bug that has gone unnoticed

are not detecting the onenand clock rate properly unless we have
CONFIG_OMAP_GPMC_DEBUG set and this causes onenand corruption
that can be easily be reproduced.
There seems to be also an additional bug still lurking around for
onenand corruption. But that is still being investigated and
it does not seem to be GPMC timings related.
Meanwhile, it would be good to get this fix into v4.4 to prevent
wrong timings from corrupting onenand.

Add a defconfig covering all known pxa board, ie. all selectable machine
files in arch/arm/mach-pxa/*.c.
This defconfig was built by doing :
- aggregation of all known defconfigs by cat
am200epdkit_defconfig
cm_x2xx_defconfig
cm_x300_defconfig
colibri_pxa270_defconfig
colibri_pxa300_defconfig

pxa3xx_defconfig
raumfeld_defconfig
spitz_defconfig
trizeps4_defconfig
viper_defconfig
xcep_defconfig
zeus_defconfig
- manual make menuconfig to ensure :
- all pxa implementation were selected
- all drivers were transformed into modules rather than builtin
=> as a consequence this single kernel will rely on an initramfs
=> as kernel size matters on pxa, each machine can take the subset
of modules required for it to work
- all missed configurations are selected verified by :
=> grep -i pxa .config | grep "is not set"
=> this should only show the left on purpose options (either not
selectable or sharpsl exception below)
- CONFIG_PXA_SHARPSL was disabled
This breaks the boot very early on any non Sharp platform, see
head-sharpsl.S
This defconfig was tested as booting up to the login phase on :
- lubbock (pxa25x)
- mainstone (pxa27x)
- zylonite (pxa3xx)
The completion of this work will require to :
- parse manually all the arch/arm/mach-pxa/*c files, look for all
platform devices added, and verify they are all in pxa_defconfig
- do the same to ensure all pxa specific drivers (leds, gpio, ...) are
included

Commit 69fb4dcada ("power: Add an axp20x-usb-power driver") introduced a
new driver for the USB power supply used on various Allwinner based SBCs.
However, the driver was not added to multi_v7_defconfig which breaks USB
support for some boards (e.g. LeMaker BananaPi) as the kernel will now
turn off the USB power supply during boot by default if the driver isn't
present. (This was not the case in linux 4.3 or lower where the USB power
was always left on.)
Hence, add the driver to multi_v7_defconfig in order to keep USB support
working on those boards that require it.

Commit 0976c946a6
"arm/versatile: Fix versatile irq specifications"
has an off-by-one error on the Versatile AB that has
been regressing the Versatile AB hardware for some time.
However it seems like the interrupt assignments have
never been correct and I have now adjusted them according
to the specification. The masks for the valid interrupts
made it impossible to assign the right SIC interrupt
for the MMCI, so I went in and fixed these to correspond
to the specifications, and added references if anyone
wants to double-check.
Due to the Versatile PB including the Versatile AB
as a base DTS file, we need to override and correct
some values to correspond to the actual changes in the
hardware.
For the Versatile PB I don't think the IRQ line
assignment for MMCI has ever been correct for either of
the two MMCI blocks. It would be nice if someone with the
physical PB board could test this.
Patch tested on the Versatile AB, QEMU for Versatile AB
and QEMU for Versatile PB.

This updates the Versatile defconfig to:
- Use NO_HZ_IDLE and HIGH_RES_TIMERS
- Enable the I2C driver
- Enable the SPI driver
- Enable the RTC driver for DS1338 as found on the Versatile
boards
- Compile in the MMCI MMC driver, which is good if you
want to mount a root FS on the MMC card without having
to first load this module from an initramfs

The Nomadik has sporadic crashes because of these latencies, setting
them to max makes the platform work nicely, so use this values for
now.
These latencies were set to 2 since the Nomadik platform was merged,
but I suspect they never took effect until the right size and
associativity for the cache was specified in the device tree and
that is why the crash comes now.

Commit 63aa945b10 ("memory: omap-gpmc: Add Kconfig option for debug")
unified the GPMC debug for the SoCs with GPMC. The commit also left out
the option for HWMOD_INIT_NO_RESET as we now require proper timings for
GPMC to be able to remap GPMC devices out of address 0.
Unfortunately on Nokia N900, onenand now only partially works with the
device tree provided timings. It works enough to get detected but the
clock rate supported by the onenand chip gets misdetected. This in turn
causes the GPMC timings to be miscalculated and this leads into file
system corruption on N900.
Looks like onenand needs CS_CONFIG1 bit 27 WRITETYPE set for for sync
write. This is needed also for async timings when we write to onenand
with omap2_onenand_set_async_mode(). Without sync write bit set, the
async read for the onenand ONENAND_REG_VERSION_ID will return 0xfff.
Let's exit with an error if onenand rate is not detected. And let's
remove the extra call to omap2_onenand_set_async_mode() as we only need
to do this once at the end of omap2_onenand_setup_async().

The separate struct bgpio_chip has been a pain to handle, both
by being confusingly similar in name to struct gpio_chip and
for being contained inside a struct so that struct gpio_chip
is contained in a struct contained in a struct, making several
steps of dereferencing necessary.
Make things simpler: include the fields directly into
<linux/gpio/driver.h>, #ifdef:ed for CONFIG_GENERIC_GPIO, and
get rid of the <linux/basic_mmio_gpio.h> altogether. Prefix
some of the member variables with bgpio_* and add proper
kerneldoc while we're at it.
Modify all users to handle the change and use a struct
gpio_chip directly. And while we're at it: replace all
container_of() dereferencing by gpiochip_get_data() and
registering the gpio_chip with gpiochip_add_data().

This implements UEFI kernel support for 32-bit ARM, based on the existing
arm64 support and existing generic early ioremap support. It is based on
commit f7d9248942 ("arm64/efi: refactor EFI init and runtime code for
reuse by 32-bit ARM"), which was pulled from the arm64 repo [1] as branch
'aarch64/efi'
[1] git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux.git
The PJ4 inline asm sequence to write to cp15 cannot be built in Thumb-2
mode, due to the way it performs arithmetic on the program counter, so it
is built in ARM mode instead. However, building C files in ARM mode under
CONFIG_THUMB2_KERNEL is problematic, since the instrumentation performed
by subsystems like ftrace does not expect having to deal with interworking
branches.
Since the sequence in question is simply a poor man's ISB instruction,
let's use a straight 'isb' instead when building in Thumb2 mode. Thumb2
implies V7, so 'isb' should always be supported in that case.

Commit 69fb4dcada ("power: Add an axp20x-usb-power driver") introduced a new
driver for the USB power supply used on various Allwinner based SBCs. However,
the driver was not added to sunxi_defconfig which breaks USB support for some
boards (e.g. LeMaker BananaPi) as the kernel will now turn off the USB power
supply during boot by default if the driver isn't present. (This was not the
case in linux 4.3 or lower where the USB power was always left on.)
Hence, add the driver to sunxi_defconfig in order to keep USB support working
on those boards that require it.

- pinctrl using the pinctrl defines as for am33xx
- Updated EDMA bindings with support for using exma_xbar
- MMC support for dm814x-evm, t410 and dra62x-j5eco-evm
- USB support for dm814x-evm, t410 and dra62x-j5eco-evm
This branch depends on an earlier omap-for-v4.5/81xx-fixes-signed

because of issues with the device tree defined clocks that just

versatile_defconfig has not been a reasonable default for a very long

based on an old ARM926 CPU core.
This changes the default to multi_v7_defconfig, which is much more
relevant to anyone doing a build test on ARM, as it covers a wide

DWC3 device found on Exynos SoCs cannot work in OTG mode alone, because
it lacks some OTG related control part. OTG mode operation is possible
only with external hardware logic (usually GPIO-based) specific to
the board. Right now, however, there is no driver for such logic and no
bindings, so the OTG mode is dysfunctional at all (this means that it
doesn't work as a peripheral nor as a host). This patch sets the operation
mode to peripheral to get DWC3_1 device at least somehow working. This can
be later updated, when proper OTG driver and bindings get developed.

Switch to use the ti,edma3-tpcc and ti,edma3-tptc binding for the eDMA3.
With the new bindings boards can customize and tweak the DMA channel
priority to match their needs. With the new binding the memcpy is safe
to be used since with the old binding it was not possible for a driver
to know which channel is allowed to be used as non HW triggered channel.
Using the new binding will allow us to reserve PaRAM slots to be used by
the DSP which was not possible before and prevented the da850 boards to be
moved to DT only.
Note that the DMA memcpy is disabled, it can be enabled by reserving
channels for memcpy by adding the following property to the edma node:
ti,edma-memcpy-channels = <20 21>; /* Reserving channel 20 and 21 for memcpy */
