arch/arm/mach-tegra/pm.c, kernel/power/console.c and mm/vmpressure.c
were somehow getting slab.h indirectly through cgroup.h which in turn
was getting it indirectly through xattr.h. A scheduled cgroup change
drops xattr.h inclusion from cgroup.h and breaks compilation of these
three files. Add explicit slab.h includes to the three files.
A pending cgroup patch depends on this change and it'd be great if
this can be routed through cgroup/for-3.14-fixes branch.

Here's a set of patches for (hopefully) -rc1. Some of them are fixes,
but a good number of them also do things such as enable new drivers in
the defconfigs for platforms that have such devices, increases coverage
of the multiplatform defconfig and some DTS changes that plumbs up some
of the devices that now have bindings and driver support.

The commit dates are recent; we've mostly collected these fixes in the

out some internal conflicts which reset the timestamps. The changes
should have been tested by each platform maintainer already (and few
of them have cross-platform impact) so I'm personally not too

TI_EDMA fell out of automatically selected options in the multi_v7
defconfig due to a select being removed from the davinci Kconfig entry. So
we need to re-enable explicitly to not regress some platforms.
The rest is just the result of running 'make multi_v7_defconfig + make
savedefconfig' to remove entries that are no longer needed due to changed
dependencies/selects or defaults.

DEBUG_FS used to be selected by COMMON_CLK_DEBUG, which was enabled
by tegra_defconfig. However, this config option no longer exists, so
no longer selects DEBUG_FS, and nothing else selects it either. So,
"make tegra_defconfig" no longer enables DEBUG_FS in .config.
Rebuild tegra_defconfig on top of next-20140424, while manually
re-enabling DEBUG_FS.
Reasons for removed entries are:
- I2C_MUX: selected by MEDIA_SUBDRV_AUTOSELECT
- DRM_PANEL: selected by DRM_TEGRA
- NEW_LEDS: selected by many things; at least VT
- LEDS_CLASS: selected by many things; at least VT

multi_v7_defconfig was missing a large number of options that were in
tegra_defconfig. This patch adds them. The changes fall into the
following categories:
* Enable more Tegra SoC options/drivers.
* Enable more drivers for Tegra boards.
* Enable more options that are useful for running distros.
The patch removes a few lines as well, simply because those options are
now selected by something else, and "make savedefconfig" removes them. I
verified that the options appear in .config after
"make multi_v7_defconfig".

On ARM, address size can be 32 bits or 64 bits (if CONFIG_ARCH_PHYS_ADDR_T_64BIT
is enabled).
We can't assume that the grant frame base address will always fits in an
unsigned long. Use phys_addr_t instead of unsigned long as argument for
gnttab_setup_auto_xlat_frames.

The use of phys_to_machine and machine_to_phys in the phys<=>bus conversions
causes us to lose the top bits of the DMA address if the size of a DMA address is not the same as the size of the phyiscal address.
This can happen in practice on ARM where foreign pages can be above 4GB even
though the local kernel does not have LPAE page tables enabled (which is
totally reasonable if the guest does not itself have >4GB of RAM). In this
case the kernel still maps the foreign pages at a phys addr below 4G (as it
must) but the resulting DMA address (returned by the grant map operation) is
much higher.
This is analogous to a hardware device which has its view of RAM mapped up
high for some reason.
This patch makes I/O to foreign pages (specifically blkif) work on 32-bit ARM
systems with more than 4GB of RAM.

Event channels driver needs to be initialized very early. Until now, Xen
initialization was done after all CPUs was bring up.
We can safely move the initialization to an early initcall.
Also use a cpu notifier to:
- Register the VCPU when the CPU is prepared
- Enable event channel IRQ when the CPU is running

Some SoC have MMIO regions that are shared across orthogonal
subsystems. This commit implements a possible solution for the
thread-safe access of such regions through a spinlock-protected API.
Concurrent access is protected with a single spinlock for the
entire MMIO address space. While this protects shared-registers,
it also serializes access to unrelated/unshared registers.
We add relaxed and non-relaxed variants, by using writel_relaxed and writel,
respectively. The rationale for this is that some users may not require
register write completion but only thread-safe access to a register.

- New driver for the Broadcom BC63xx HSSPI controller.
- Fix duplicate device registration for ACPI.
- Conversion of s3c64xx to DMAEngine (this pulls in platform and DMA
changes upon which the transiton depends).
- Some small optimisations to reduce the amount of time we hold locks

Pull thermal management updates from Zhang Rui:
"This time, the biggest change is the work of representing hardware
thermal properties in device tree infrastructure.
This work includes the introduction of a device tree bindings for
describing the hardware thermal behavior and limits, and also a parser
to read and interpret the data, and build thermal zones and thermal
binding parameters. It also contains three examples on how to use the
new representation on sensor devices, using three different drivers to
accomplish it. One driver is in thermal subsystem, the TI SoC
thermal, and the other two drivers are in hwmon subsystem.
Actually, this would be the first step of the complete work because we
still need to check other potential drivers to be converted and then
validate the proposed API. But the reason why I include it in this
pull request is that, first, this change does not hurt any others
without using this approach, second, the principle and concept of this
change would not break after converting the remaining drivers. BTW,
as you can see, there are several points in this change that do not
belong to thermal subsystem. Because it has been suggested by Guenter
R that in such cases, it is recommended to send the complete series
via one single subsystem.
Specifics:
- representing hardware thermal properties in device tree
infrastructure
- fix a regression that the imx thermal driver breaks system suspend.
- introduce ACPI INT3403 thermal driver to retrieve temperature data
from the INT3403 ACPI device object present on some systems.
- introduce debug statement for thermal core and step_wise governor.
- assorted fixes and cleanups for thermal core, cpu cooling, exynos
thrmal, intel powerclamp and imx thermal driver"

Pull ACPI and power management updates from Rafael Wysocki:
"As far as the number of commits goes, the top spot belongs to ACPI
this time with cpufreq in the second position and a handful of PM
core, PNP and cpuidle updates. They are fixes and cleanups mostly, as
usual, with a couple of new features in the mix.
The most visible change is probably that we will create struct
acpi_device objects (visible in sysfs) for all devices represented in
the ACPI tables regardless of their status and there will be a new
sysfs attribute under those objects allowing user space to check that
status via _STA.
Consequently, ACPI device eject or generally hot-removal will not
delete those objects, unless the table containing the corresponding
namespace nodes is unloaded, which is extremely rare. Also ACPI
container hotplug will be handled quite a bit differently and cpufreq
will support CPU boost ("turbo") generically and not only in the
acpi-cpufreq driver.
Specifics:
- ACPI core changes to make it create a struct acpi_device object for
every device represented in the ACPI tables during all namespace
scans regardless of the current status of that device. In
accordance with this, ACPI hotplug operations will not delete those
objects, unless the underlying ACPI tables go away.

DT and DT-conversion-related changes for various ARM platforms. Most
of these are to enable various devices on various boards, etc, and not
necessarily worth enumerating.
New boards and systems continue to come in as new devicetree files that
don't require corresponding C changes any more, which is indicating that
the system is starting to work fairly well.
A few things worth pointing out:
* ST Ericsson ux500 platforms have made the major push to move over to fully
support the platform with DT.
* Renesas platforms continue their conversion over from legacy platform devices
to DT-based for hardware description.

This is the branch where we usually queue up cleanup efforts, moving
drivers out of the architecture directory, header file restructuring,
etc. Sometimes they tangle with new development so it's hard to keep it
strictly to cleanups.
Some of the things included in this branch are:
* Atmel SAMA5 conversion to common clock
* Reset framework conversion for tegra platforms
- Some of this depends on tegra clock driver reworks that are shared with Mike
Turquette's clk tree.
* Tegra DMA refactoring, which are shared branches with the DMA tree.
* Removal of some header files on exynos to prepare for multiplatform

- FIFO event channels. Key advantages: support for over 100,000 events (2^17),
16 different event priorities, improved fairness in event latency through
the use of FIFOs.
- Xen PVH support. "It’s a fully PV kernel mode, running with paravirtualized
disk and network, paravirtualized interrupts and timers, no emulated devices
of any kind (and thus no qemu), no BIOS or legacy boot — but instead of
requiring PV MMU, it uses the HVM hardware extensions to virtualize the
pagetables, as well as system calls and other privileged operations."
(from "The Paravirtualization Spectrum, Part 2: From poles to a spectrum")
Bug-fixes:
- Fixes in balloon driver (refactor and make it work under ARM)
- Allow xenfb to be used in HVM guests.
- Allow xen_platform_pci=0 to work properly.
- Refactors in event channels.

Pull Xen updates from Konrad Rzeszutek Wilk:
"Two major features that Xen community is excited about:
The first is event channel scalability by David Vrabel - we switch
over from an two-level per-cpu bitmap of events (IRQs) - to an FIFO
queue with priorities. This lets us be able to handle more events,
have lower latency, and better scalability. Good stuff.
The other is PVH by Mukesh Rathor. In short, PV is a mode where the
kernel lets the hypervisor program page-tables, segments, etc. With
EPT/NPT capabilities in current processors, the overhead of doing this
in an HVM (Hardware Virtual Machine) container is much lower than the
hypervisor doing it for us.
In short we let a PV guest run without doing page-table, segment,
syscall, etc updates through the hypervisor - instead it is all done
within the guest container. It is a "hybrid" PV - hence the 'PVH'
name - a PV guest within an HVM container.
The major benefits are less code to deal with - for example we only
use one function from the the pv_mmu_ops (which has 39 function
calls); faster performance for syscall (no context switches into the
hypervisor); less traps on various operations; etc.
It is still being baked - the ABI is not yet set in stone. But it is
pretty awesome and we are excited about it.
Lastly, there are some changes to ARM code - you should get a simple
conflict which has been resolved in #linux-next.
In short, this pull has awesome features.
Features:
- FIFO event channels. Key advantages: support for over 100,000
events (2^17), 16 different event priorities, improved fairness in
event latency through the use of FIFOs.
- Xen PVH support. "It’s a fully PV kernel mode, running with

Introduce memblock memory allocation APIs which allow to support PAE or
LPAE extension on 32 bits archs where the physical memory start address
can be beyond 4GB. In such cases, existing bootmem APIs which operate
on 32 bit addresses won't work and needs memblock layer which operates
on 64 bit addresses.
So we add equivalent APIs so that we can replace usage of bootmem with
memblock interfaces. Architectures already converted to NO_BOOTMEM use
these new memblock interfaces. The architectures which are still not
converted to NO_BOOTMEM continue to function as is because we still
maintain the fal lback option of bootmem back-end supporting these new
interfaces. So no functional change as such.
In long run, once all the architectures moves to NO_BOOTMEM, we can get
rid of bootmem layer completely. This is one step to remove the core
code dependency with bootmem and also gives path for architectures to
move away from bootmem.
The proposed interface will became active if both CONFIG_HAVE_MEMBLOCK
and CONFIG_NO_BOOTMEM are specified by arch. In case
!CONFIG_NO_BOOTMEM, the memblock() wrappers will fallback to the
existing bootmem apis so that arch's not converted to NO_BOOTMEM
continue to work as is.
The meaning of MEMBLOCK_ALLOC_ACCESSIBLE and MEMBLOCK_ALLOC_ANYWHERE
is kept same.

Commit 4b59e6c473 ("mm, show_mem: suppress page counts in
non-blockable contexts") introduced SHOW_MEM_FILTER_PAGE_COUNT to
suppress PFN walks on large memory machines. Commit c78e93630d ("mm:
do not walk all of system memory during show_mem") avoided a PFN walk in
the generic show_mem helper which removes the requirement for
SHOW_MEM_FILTER_PAGE_COUNT in that case.
This patch removes PFN walkers from the arch-specific implementations
that report on a per-node or per-zone granularity. ARM and unicore32
still do a PFN walk as they report memory usage on each bank which is a
much finer granularity where the debugging information may still be of
use. As the remaining arches doing PFN walks have relatively small
amounts of memory, this patch simply removes SHOW_MEM_FILTER_PAGE_COUNT.

It was holiday season, so no wonder that there are little changes in
framework level, although diffstat shows quite many changes spreaded
over sound/* directories. Most of changes are cleanups, code
refactoring and fixes.
Some highlights:
- Removal of OSS sleep_on usages by Arnd
- Simplified memalloc helper codes, drop obsoleted features;
now it's built into PCM driver instead of an individual module
- Warn if PCM buffer preallocation fails, which will show page
allocation issues more clearly
- Compress offload API updates for sample rates by Vinod
- PCM glitch workaround on ctxfi emu20k1 by Sarah
- Drop cs46xx DSP blobs, using firmware loader now
- USB-audio quitks for Plantronics Gamecom 780, Creative VF0420,
and Focusrite Saffire 6
HD-audio specifics:
- Standardize Kconfigs of HD-audio codec drivers;
now "make localmodconfig" recognizes configs properly (finally!)
- Parallel PM implementation by Mengdong
- BayleyBay/ValleyView2 board fixups
- Broadwell audio support
- Runtime PM improvement (PantherPoint, etc)
- Quirks: Dell subwooer, Gigabyte mobo jack detection oddity,
Dell AiO click noise fixes, Dell headset mic fixes, etc
- Automatic bind with HDMI codec parser without generic parser
- More AD codec fixes (since 3.12 regression) including the automatic
stereo mix support
- Common Thinkpad ACPI helper for Realtek and Conexant codecs
ASoC specifics:
- Update to the generic DMA code to support deferred probe and managed
resources
- New drivers for BCM2835 (used in Raspberry Pi), Tegra with MAX98090
and Analog Devices AXI I2S and S/PDIF controller IPs
- Device tree support for the simple card, max98090 and cs42l52
- Conversion of the Samsung drivers to native dmaengine, making them
multiplatform compatible and hopefully helping keep them more modern
and up to date.
- More regmap conversions, including a very welcome one for twl6040
from Peter Ujfalusi

A big set this merge window, as we have much going on in
this subsystem. Major changes this time:
- Some core improvements and cleanups to the new GPIO
descriptor API. This seems to be working now so we can
start the exodus to this API, moving gradually away from
the global GPIO numberspace.
- Incremental improvements to the ACPI GPIO core, and move
the few GPIO ACPI clients we have to the GPIO descriptor
API right *now* before we go any further. We actually
managed to contain this *before* we started to litter
the kernel with yet another hackish global numberspace for
the ACPI GPIOs, which is a big win.
- The RFkill GPIO driver and all platforms using it have
been migrated to use the GPIO descriptors rather than
fixed number assignments. Tegra machine has been migrated
as part of this.
- New drivers for MOXA ART, Xtensa GPIO32 and SMSC SCH311x.
Those should be really good examples of how I expect a
nice GPIO driver to look these days.
- Do away with custom GPIO implementations on a major
part of the ARM machines: ks8695, lpc32xx, mv78xx0.
Make a first step towards the same in the horribly
convoluted Samsung S3C include forest. We expect to
continue to clean this up as we move forward.
- Flag GPIO lines used for IRQ on adnp, bcm-kona, em,
intel-mid and lynxpoint.
This makes the GPIOlib core aware that a certain GPIO line
is used for IRQs and can then enforce some semantics such
as disallowing a GPIO line marked as in use for IRQ to be
switched to output mode.
- Drop all use of irq_set_chip_and_handler_name().
The name provided in these cases were just unhelpful
tags like "mux" or "demux".
- Extend the MCP23s08 driver to handle interrupts.
- Minor incremental improvements for rcar, lynxpoint, em
74x164 and msm drivers.
- Some non-urgent bug fixes here and there, duplicate
#includes and that usual kind of cleanups.

Although we allow recovery in this case, this is not supposed to be
the normal path for hotplugging a CPU back in. This path only exists
to serve those rare platforms where it's not possible to power down
the CPU or reset the CPU. This patch causes the kernel to print a
message when a platform uses this path.

If the kernel is loaded higher in physical memory than normal, and we
calculate PHYS_OFFSET higher than the start of RAM, this leads to
boot problems as we attempt to map part of this RAM into userspace.
Rather than struggle with this, just truncate the mapping.

This is because it's possible to have ZBOOT_ROM enabled, but at the

Depending on the regulator version, the voltage table might be
different. Use version specific regulator tables in order to select
correct voltage table. For the following regulator versions different
voltage tables are now used:
* TPS658623: Use correct voltage table for SM2
* TPS658643: New voltage table for SM2
Both versions are in use on the Colibri T20 module. Make use of the
correct tables by requesting the correct SM2 voltage of 1.8V.
This change is not backward compatible since an old driver is not able
to correctly set that value. The value 1.8V is out of range for the old
driver and will refuse to probe the device. The regulator starts with
default settings and the driver shows appropriate error messages.
On Colibri T20, the old value used to work with TPS658623 since the
driver applied a wrong voltage table too. However, the TPS658643 used
on V1.2 devices uses yet another voltage table and those broke that
pseudo-compatibility. The regulator driver now has the correct voltage
table for both regulator versions and those the correct voltage can be
used in the device tree.

Here's the big tty/serial driver pull request for 3.14-rc1
There are a number of n_tty fixes and cleanups, and some serial driver
bugfixes, and we got rid of one obsolete driver, making this series
remove more lines than added, always a nice surprise.
All of these have been in linux-next with no reports of issues.

Pull perf updates from Ingo Molnar:
"Kernel side changes:
- Add Intel RAPL energy counter support (Stephane Eranian)

directory with guest specific /proc information (Dongsheng Yang)
- Add shell completion support (Ramkumar Ramachandra)
- Add '-v' option (Dongsheng Yang)
- Support --guestmount (Dongsheng Yang)
- 'perf probe':
- Support showing source code, asking for variables to be collected
at probe time and other 'perf probe' operations that use DWARF
information.
This supports only binaries with debugging information at this
time, detached debuginfo (aka debuginfo packages) support should
come in later patches (Masami Hiramatsu)
- 'perf record':
- Rename --no-delay option to --no-buffering, better reflecting its
purpose and freeing up '--delay' to take the place of
'--initial-delay', so that 'record' and 'stat' are consistent
(Arnaldo Carvalho de Melo)
- Default the -t/--thread option to no inheritance (Adrian Hunter)
- Make per-cpu mmaps the default (Adrian Hunter)
- 'perf report':
- Improve callchain processing performance (Frederic Weisbecker)
- Retain bfd reference to lookup source line numbers, greatly
optimizing, among other use cases, 'perf report -s srcline'
(Adrian Hunter)
- Improve callchain processing performance even more (Namhyung Kim)
- Add a perf.data file header window in the 'perf report' TUI,
associated with the 'i' hotkey, providing a counterpart to the
--header option in the stdio UI (Namhyung Kim)
- 'perf script':
- Add an option in 'perf script' to print the source line number
(Adrian Hunter)
- Add --header/--header-only options to 'script' and 'report', the
default is not tho show the header info, but as this has been the
default for some time, leave a single line explaining how to
obtain that information (Jiri Olsa)
- Add options to show comm, fork, exit and mmap PERF_RECORD_ events
(Namhyung Kim)
- Print callchains and symbols if they exist (David Ahern)
- 'perf timechart'

other tools (David Ahern)
- 'perf trace':
- Handle old kernels where the "raw_syscalls" tracepoints were
called plain "syscalls" (David Ahern)

set the mmap size, but wasn't using it when doing the actual mmap
on the events file descriptors (Jiri Olsa)
- generic:
- Backport libtraceevent plugin support (trace-cmd repository, with
plugins for jbd2, hrtimer, kmem, kvm, mac80211, sched_switch,
function, xen, scsi, cfg80211 (Jiri Olsa)

build-test) (Namhyung Kim)
- Get rid of die() and friends (good riddance!) in libtraceevent
(Namhyung Kim)

being propagated to the feature tests, leading to features being
tested in the host and then being enabled on the target (Mark
Rutland)
- Improve forked workload error reporting by sending the errno in the
signal data queueing integer field, using sigqueue and by doing the
signal setup in the evlist methods, removing open coded equivalents
in various tools (Arnaldo Carvalho de Melo)
- Do more auto exit cleanup chores in the 'evlist' destructor, so
that the tools don't have to all do that sequence (Arnaldo Carvalho
de Melo)

memory in struct pointers to NULL, to help fixing use after free
bugs (Arnaldo Carvalho de Melo)
- Rename some struct DSO binary_type related members and methods, to
clarify its purpose and need for differentiation (symtab_type, ie
one is about the files .text, CFI, etc, i.e. its binary contents,
and the other is about where the symbol table came from (Arnaldo
Carvalho de Melo)

DT clocks are mostly missing clkdm info now, and this causes an issue with
counter32k which makes its slave idlemode wrong and prevents core idle.
Fixed by initializing the hwmod clkdm pointers for omap3 also which makes
sure the clkdm flag matching logic works properly.

incorrect clkdm_name, as this a warning, not a fatal error.

If the main clock for a hwmod is of basic clock type, it is illegal to type
cast this to clk_hw_omap and will result in bogus data. Fixed by checking
the clock flags before attempting the type cast.

Clock nodes shall use the services provided by underlying drivers to access
the hardware registers instead of direct memory read/write. Thus, change
all the code to use the new omap2_clk_readl / omap2_clk_writel APIs for this.

Merge tag 'davinci-for-v3.14/soc' of git://git.kernel.org/pub/scm/linux/kernel/git/nsekhar/linux-davinci into next/soc
From Sekhar Nori:
A patch to fix the return value of clk_round_rate()
* tag 'davinci-for-v3.14/soc' of git://git.kernel.org/pub/scm/linux/kernel/git/nsekhar/linux-davinci:
ARM: davinci: clock: return 0 upon error from clk_round_rate()
DT-enabled Marvell Kirkwood and Dove SoCs make use of an irqchip
driver. As expected for irqchip drivers, it uses a C-style
interrupt handler and therefore selects MULTI_IRQ_HANDLER.
Now, compiling a kernel with both non-DT and DT support enabled,
selecting MULTI_IRQ_HANDLER will break ASM irq handler used by
non-DT boards.
Therefore, we provide a C-style irq handler even for non-DT boards,
if MULTI_IRQ_HANDLER is set. By installing the C-style irq handler
in orion_irq_init this is transparent to all non-DT board files.
While the regression report was filed on Marvell Kirkwood, also
Marvell Dove non-DT boards are affected and fixed by this patch.

device_type is deprecated and the kernel doesn't require it in most
cases. The only exceptions for flat tree users are the "gianfar",
"ucc_geth" and "ibm,emac" bindings, and arguably that requirement could
be relaxed for ucc_geth and ibm,emac (that is a task for separate
patches though).
This patch removes references to device_type="network" from the binding
documentation where possible and removes the properties from ARM and
microblaze dts files. This patch does not modify the powerpc .dts files
since there are a much larger number of them affected and I think the
ucc_geth, ibm,emac and gianfar users should be addressed before clearing
out the references to reduce the chance of breakage.
