Merge tag 'acpica-4.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull ACPICA updates from Rafael Wysocki:
"Additional ACPICA material for v4.2-rc1
This will update the ACPICA code in the kernel to upstream revision
20150619 (a bug-fix release mostly including stable-candidate fixes)
and restore an earlier ACPICA commit that had to be reverted due to a
regression introduced by it (the regression is addressed by
blacklisting the only known system affected by it to date).
The only new feature added by this update is the support for
overriding objects in the ACPI namespace and a new ACPI table that can
be used for that called the Override System Definition Table (OSDT).
That should allow us to "patch" the ACPI namespace built from
incomplete or incorrect ACPI System Definition tables (DSDT, SSDT)
during system startup without the need to provide replacements for all
of those tables in the future.
Specifics:
- Fix system resume problems related to 32-bit and 64-bit versions of
the Firmware ACPI Control Structure (FACS) in the firmare (Lv
Zheng)
- Fix double initialization of the FACS (Lv Zheng)
- Add _CLS object processing code to ACPICA (Suravee Suthikulpanit)

ACPI / init: Make it possible to override _REV
The platform firmware on some systems expects Linux to return "5" as the supported ACPI revision which makes it expose system configuration information in a special way. For example, based on what ACPI exports as the supported revision, Dell XPS 13 (2015) configures its audio device to either work in HDA mode or in I2S mode, where the former is supposed to be used on Linux until the latter is fully supported (in the kernel as well as in user space). Since ACPI 6 mandates that _REV should return "2" if ACPI 2 or later is supported by the OS, a subsequent change will make that happen, so make it possible to override that on systems where "5" is expected to be returned for Linux to work correctly one them (such as the Dell machine mentioned above).

An input queue and a processing queue is split out from the monolithic fuse connection, each of those having their own spinlock. The end of the patchset adds the ability to clone a fuse connection. This means, that instead of having to read/write requests/answers on a single fuse device fd, the fuse daemon can have multiple distinct file descriptors open. Each of those can be used to receive requests and send answers, currently the only constraint is that a request must be answered on the same fd as it was read from. This can be extended further to allow binding a device clone to a specific CPU or NUMA node. Based on a patchset by Srinivas Eeda and Ashish Samant.

fs/file.c: don't acquire files->file_lock in fd_install()
Mateusz Guzik reported : Currently obtaining a new file descriptor results in locking fdtable twice - once in order to reserve a slot and second time to fill it. Holding the spinlock in __fd_install() is needed in case a resize is done, or to prevent a resize. Mateusz provided an RFC patch and a micro benchmark : http://people.redhat.com/~mguzik/pipebench.c A resize is an unlikely operation in a process lifetime, as table size is at least doubled at every resize. We can use RCU instead of the spinlock. __fd_install() must wait if a resize is in progress. The resize must block new __fd_install() callers from starting, and wait that ongoing install are finished (synchronize_sched()) resize should be attempted by a single thread to not waste resources. rcu_sched variant is used, as __fd_install() and expand_fdtable() run from process context. It gives us a ~30% speedup using pipebench on a dual Intel(R) Xeon(R) CPU E5-2696 v2 @ 2.50GHz Signed-off-by: Eric Dumazet <edumazet@google.com> Reported-by: Mateusz Guzik <mguzik@redhat.com> Acked-by: Mateusz Guzik <mguzik@redhat.com> Tested-by: Mateusz Guzik <mguzik@redhat.com> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> |

net: mvneta: introduce compatible string "marvell, armada-xp-neta"
The mvneta driver supports the Ethernet IP found in the Armada 370, XP,
380 and 385 SoCs. Since at least one more hardware feature is available
for the Armada XP SoCs then a way to identify them is needed.
This patch introduces a new compatible string "marvell,armada-xp-neta".

The libnvdimm sub-system introduces, in addition to the libnvdimm-core,
4 drivers / enabling modules:
NFIT:
Instantiates an "nvdimm bus" with the core and registers memory devices
(NVDIMMs) enumerated by the ACPI 6.0 NFIT (NVDIMM Firmware Interface
table). After registering NVDIMMs the NFIT driver then registers
"region" devices. A libnvdimm-region defines an access mode and the
boundaries of persistent memory media. A region may span multiple
NVDIMMs that are interleaved by the hardware memory controller. In
turn, a libnvdimm-region can be carved into a "namespace" device and
bound to the PMEM or BLK driver which will attach a Linux block device
(disk) interface to the memory.
PMEM:
Initially merged in v4.1 this driver for contiguous spans of persistent
memory address ranges is re-worked to drive PMEM-namespaces emitted by
the libnvdimm-core. In this update the PMEM driver, on x86, gains the
ability to assert that writes to persistent memory have been flushed all
the way through the caches and buffers in the platform to persistent
media. See memcpy_to_pmem() and wmb_pmem().
BLK:
This new driver enables access to persistent memory media through "Block
Data Windows" as defined by the NFIT. The primary difference of this
driver to PMEM is that only a small window of persistent memory is
mapped into system address space at any given point in time. Per-NVDIMM
windows are reprogrammed at run time, per-I/O, to access different
portions of the media. BLK-mode, by definition, does not support DAX.
BTT:
This is a library, optionally consumed by either PMEM or BLK, that
converts a byte-accessible namespace into a disk with atomic sector
update semantics (prevents sector tearing on crash or power loss). The
sinister aspect of sector tearing is that most applications do not know
they have a atomic sector dependency. At least today's disk's rarely
ever tear sectors and if they do one almost certainly gets a CRC error
on access. NVDIMMs will always tear and always silently. Until an
application is audited to be robust in the presence of sector-tearing
the usage of BTT is recommended.

Merge branch 'drm-next' of git://people.freedesktop.org/~airlied/linux
Pull drm updates from Dave Airlie:
"This is the main drm pull request for v4.2.
I've one other new driver from freescale on my radar, it's been posted
and reviewed, I'd just like to get someone to give it a last look, so
maybe I'll send it or maybe I'll leave it.
There is no major nouveau changes in here, Ben was working on
something big, and we agreed it was a bit late, there wasn't anything
else he considered urgent to merge.
There might be another msm pull for some bits that are waiting on
arm-soc, I'll see how we time it.
This touches some "of" stuff, acks are in place except for the fixes
to the build in various configs,t hat I just applied.
Summary:
New drivers:
- virtio-gpu:
KMS only pieces of driver for virtio-gpu in qemu.
This is just the first part of this driver, enough to run
unaccelerated userspace on. As qemu merges more we'll start
adding the 3D features for the virgl 3d work.
- amdgpu:
a new driver from AMD to driver their newer GPUs. (VI+)
It contains a new cleaner userspace API, and is a clean
break from radeon moving forward, that AMD are going to
concentrate on. It also contains a set of register headers
auto generated from AMD internal database.
core:
- atomic modesetting API completed, enabled by default now.
- Add support for mode_id blob to atomic ioctl to complete interface.
- bunch of Displayport MST fixes
- lots of misc fixes.
panel:
- new simple panels
- fix some long-standing build issues with bridge drivers
radeon:
- VCE1 support
- add a GPU reset counter for userspace
- lots of fixes.
amdkfd:
- H/W debugger support module
- static user-mode queues
- support killing all the waves when a process terminates
- use standard DECLARE_BITMAP
i915:
- Add Broxton support
- S3, rotation support for Skylake
- RPS booting tuning
- CPT modeset sequence fixes
- ns2501 dither support
- enable cmd parser on haswell
- cdclk handling fixes
- gen8 dynamic pte allocation
- lots of atomic conversion work
exynos:
- Add atomic modesetting support
- Add iommu support
- Consolidate drm driver initialization
- and MIC, DECON and MIPI-DSI support for exynos5433
omapdrm:
- atomic modesetting support (fixes lots of things in rewrite)
tegra:
- DP aux transaction fixes
- iommu support fix
msm:
- adreno a306 support
- various dsi bits
- various 64-bit fixes
- NV12MT support
rcar-du:
- atomic and misc fixes
sti:
- fix HDMI timing complaince
tilcdc:
- use drm component API to access tda998x driver
- fix module unloading
qxl:
- stability fixes"

Merge branch 'for-linus' of git://ftp.arm.linux.org.uk/~rmk/linux-arm
Pull ARM updates from Russell King:
"Bigger items included in this update are:
- A series of updates from Arnd for ARM randconfig build failures
- Updates from Dmitry for StrongARM SA-1100 to move IRQ handling to
drivers/irqchip/
- Move ARMs SP804 timer to drivers/clocksource/
- Perf updates from Mark Rutland in preparation to move the ARM perf
code into drivers/ so it can be shared with ARM64.
- MCPM updates from Nicolas
- Add support for taking platform serial number from DT
- Re-implement Keystone2 physical address space switch to conform to
architecture requirements
- Clean up ARMv7 LPAE code, which goes in hand with the Keystone2
changes.
- L2C cleanups to avoid unlocking caches if we're prevented by the
secure support to unlock.
- Avoid cleaning a potentially dirty cache containing stale data on
CPU initialisation
- Add ARM-only entry point for secondary startup (for machines that
can only call into a Thumb kernel in ARM mode). Same thing is also
done for the resume entry point.
- Provide arch_irqs_disabled via asm-generic
- Enlarge ARMv7M vector table
- Always use BFD linker for VDSO, as gold doesn't accept some of the
options we need.
- Fix an incorrect BSYM (for Thumb symbols) usage, and convert all
BSYM compiler macros to a "badr" (for branch address).
- Shut up compiler warnings provoked by our cmpxchg() implementation.
- Ensure bad xchg sizes fail to link"

nd_btt: atomic sector updates
BTT stands for Block Translation Table, and is a way to provide power fail sector atomicity semantics for block devices that have the ability to perform byte granularity IO. It relies on the capability of libnvdimm namespace devices to do byte aligned IO. The BTT works as a stacked blocked device, and reserves a chunk of space from the backing device for its accounting metadata. It is a bio-based driver because all IO is done synchronously, and there is no queuing or asynchronous completions at either the device or the driver level. The BTT uses 'lanes' to index into various 'on-disk' data structures, and lanes also act as a synchronization mechanism in case there are more CPUs than available lanes. We did a comparison between two lane lock strategies - first where we kept an atomic counter around that tracked which was the last lane that was used, and 'our' lane was determined by atomically incrementing that. That way, for the nr_cpus > nr_lanes case, theoretically, no CPU would be blocked waiting for a lane. The other strategy was to use the cpu number we're scheduled on to and hash it to a lane number. Theoretically, this could block an IO that could've otherwise run using a different, free lane. But some fio workloads showed that the direct cpu -> lane hash performed faster than tracking 'last lane' - my reasoning is the cache thrash caused by moving the atomic variable made that approach slower than simply waiting out the in-progress IO. This supports the conclusion that the driver can be a very simple bio-based one that does synchronous IOs instead of queuing.

sound updates for 4.2-rc1
It was a busy development cycle at this time, as you can see a wide
range of changes in diffstat. There are no big changes but many
refactoring and improvements. Here we go some highlights:
* ALSA core:
- Procfs codes were cleaned up to use seq_file
- Procfs can be opt out via Kconfig (only for EXPERT)
- Two types of jack API were unified finally; now both kctl and input
jack devs are handled via a single function call.
* HD-audio
- Continued code restructuring for the future ASoC driver; now HDA
controller driver is split to a core helper module.
- Preliminary codes for Skylake audio support in HDA core.
- Proper i915 gfx power well management for SKL & co
- Enabled runtime PM as default for Intel HDMI/DP codecs
- Newer Tegra chip supports
- More quirks for Dell headsets, Alienware (with CA0132), etc.
- A couple of DRM ELD helper API functions
* ASoC
- Support for loading ASoC topology maps from firmware, intended to be
used to allow self-describing DSP firmware images to be built which
can map controls added by the DSP to userspace without the kernel
needing to know about individual DSP firmwares
- Lots of refactoring to avoid direct access to snd_soc_codec where
it's not needed supporting future refactoring
- Big refactoring, cleanup and enhancement for the Wolfson ADSP driver
- Cleanup series for TI TAS2552 and R-CAR drivers
- Fixes and improvements on RT56xx codecs
- Support for TI TAS571x power amplifiers

Merge tag 'sound-4.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound
Pull sound updates from Takashi Iwai:
"It was a busy development cycle at this time, as you can see a wide
range of changes in diffstat. There are no big changes but many
refactoring and improvements. Here we go some highlights:
ALSA core:
- Procfs codes were cleaned up to use seq_file
- Procfs can be opt out via Kconfig (only for EXPERT)
- Two types of jack API were unified finally; now both kctl and input
jack devs are handled via a single function call.
HD-audio:
- Continued code restructuring for the future ASoC driver; now HDA
controller driver is split to a core helper module.
- Preliminary codes for Skylake audio support in HDA core.
- Proper i915 gfx power well management for SKL & co
- Enabled runtime PM as default for Intel HDMI/DP codecs
- Newer Tegra chip supports
- More quirks for Dell headsets, Alienware (with CA0132), etc.
- A couple of DRM ELD helper API functions
ASoC:
- Support for loading ASoC topology maps from firmware, intended to
be used to allow self-describing DSP firmware images to be built
which can map controls added by the DSP to userspace without the
kernel needing to know about individual DSP firmwares
- Lots of refactoring to avoid direct access to snd_soc_codec where
it's not needed supporting future refactoring
- Big refactoring, cleanup and enhancement for the Wolfson ADSP
driver
- Cleanup series for TI TAS2552 and R-CAR drivers
- Fixes and improvements on RT56xx codecs
- Support for TI TAS571x power amplifiers
- Support for Qualcomm APQ8016 and ZTE ZX296702 SoCs

coredump: use from_kuid/kgid when formatting corename
When adding __printf attribute to cn_printf, gcc reports some issues:
fs/coredump.c:213:5: warning: format '%d' expects argument of type
'int', but argument 3 has type 'kuid_t' [-Wformat=]
err = cn_printf(cn, "%d", cred->uid);
^
fs/coredump.c:217:5: warning: format '%d' expects argument of type
'int', but argument 3 has type 'kgid_t' [-Wformat=]
err = cn_printf(cn, "%d", cred->gid);
^
These warnings come from the fact that the value of uid/gid needs to be
extracted from the kuid_t/kgid_t structure before being used as an
integer. More precisely, cred->uid and cred->gid need to be converted to
either user-namespace uid/gid or to init_user_ns uid/gid.
Use init_user_ns in order not to break existing ABI, and document this in
Documentation/sysctl/kernel.txt.
While at it, format uid and gid values with %u instead of %d because
uid_t/__kernel_uid32_t and gid_t/__kernel_gid32_t are unsigned int.

netconsole: implement extended console support
printk logbuf keeps various metadata and optional key=value dictionary for structured messages, both of which are stripped when messages are handed to regular console drivers. It can be useful to have this metadata and dictionary available to netconsole consumers. This obviously makes logging via netconsole more complete and the sequence number in particular is useful in environments where messages may be lost or reordered in transit - e.g. when netconsole is used to collect messages in a large cluster where packets may have to travel congested hops to reach the aggregator. The lost and reordered messages can easily be identified and handled accordingly using the sequence numbers. printk recently added extended console support which can be selected by setting CON_EXTENDED flag. From console driver side, not much changes. The only difference is that the text passed to the write callback is formatted the same way as /dev/kmsg. This patch implements extended console support for netconsole which can be enabled by either prepending "+" to a netconsole boot param entry or echoing 1 to "extended" file in configfs. When enabled, netconsole transmits extended log messages with headers identical to /dev/kmsg output. There's one complication due to message fragments. netconsole limits the maximum message size to 1k and messages longer than that are split into multiple fragments. As all extended console messages should carry matching headers and be uniquely identifiable, each extended message fragment carries full copy of the metadata and an extra header field to identify the specific fragment. The optional header is of the form "ncfrag=OFF/LEN" where OFF is the byte offset into the message body and LEN is the total length. To avoid unnecessarily making printk format extended messages, Extended netconsole is registered with printk when the first extended netconsole is configured.

printk: implement support for extended console drivers
printk log_buf keeps various metadata for each message including its sequence number and timestamp. The metadata is currently available only through /dev/kmsg and stripped out before passed onto console drivers. We want this metadata to be available to console drivers too so that console consumers can get full information including the metadata and dictionary, which among other things can be used to detect whether messages got lost in transit. This patch implements support for extended console drivers. Consoles can indicate that they want extended messages by setting the new CON_EXTENDED flag and they'll be fed messages formatted the same way as /dev/kmsg. "<level>,<sequnum>,<timestamp>,<contflag>;<message text>\n" If extended consoles exist, in-kernel fragment assembly is disabled. This ensures that all messages emitted to consoles have full metadata including sequence number. The contflag carries enough information to reassemble the fragments from the reader side trivially. Note that this only affects /dev/kmsg. Regular console and /proc/kmsg outputs are not affected by this change. * Extended message formatting for console drivers is enabled iff there are registered extended consoles. * Comment describing /dev/kmsg message format updated to add missing contflag field and help distinguishing variable from verbatim terms.

zram: add dynamic device add/remove functionality
We currently don't support on-demand device creation. The one and only way to have N zram devices is to specify num_devices module parameter (default value: 1). IOW if, for some reason, at some point, user wants to have N + 1 devies he/she must umount all the existing devices, unload the module, load the module passing num_devices equals to N + 1. And do this again, if needed. This patch introduces zram control sysfs class, which has two sysfs attrs: - hot_add -- add a new zram device - hot_remove -- remove a specific (device_id) zram device hot_add sysfs attr is read-only and has only automatic device id assignment mode (as requested by Minchan Kim). read operation performed on this attr creates a new zram device and returns back its device_id or error status. Usage example: # add a new specific zram device cat /sys/class/zram-control/hot_add 2 # remove a specific zram device echo 4 > /sys/class/zram-control/hot_remove Returning zram_add() error code back to user (-ENOMEM in this case) cat /sys/class/zram-control/hot_add cat: /sys/class/zram-control/hot_add: Cannot allocate memory NOTE, there might be users who already depend on the fact that at least zram0 device gets always created by zram_init().

zram: add compact sysfs entry to documentation
We currently don't support zram on-demand device creation. The only way
to have N zram devices is to specify num_devices module parameter (default
value 1). That means that if, for some reason, at some point, user wants
to have N + 1 devies he/she must umount all the existing devices, unload
the module, load the module passing num_devices equals to N + 1.
This patchset introduces zram-control sysfs class, which has two sysfs

- hot_remove -- remove a specific (device_id) zram device
Usage example:
# add a new specific zram device
cat /sys/class/zram-control/hot_add
1
# remove a specific zram device
echo 4 > /sys/class/zram-control/hot_remove
This patch (of 10):

But for situation when /dev/mem usage is disabled, the utils have to use dmi sysfs instead, which doesn't represent SMBIOS entry and adds code/delay redundancy when direct access for table is needed. So this patch creates dmi/tables and adds SMBIOS entry point to allow utils in question to work correctly without /dev/mem. Also patch adds raw dmi table to simplify dmi table processing in user space, as proposed by Jean Delvare.

ARM: SoC: driver updates for v4.2
Some of these are for drivers/soc, where we're now putting SoC-specific drivers these days. Some are for other driver subsystems where we have received acks from the appropriate maintainers. Some highlights: - simple-mfd: document DT bindings and misc updates - migrate mach-berlin to simple-mfd for clock, pinctrl and reset - memory: support for Tegra132 SoC - memory: introduce tegra EMC driver for scaling memory frequency - misc. updates for ARM CCI and CCN busses Conflicts: arch/arm64/boot/dts/arm/juno-motherboard.dtsi Trivial add/add conflict with our dt branch.

Pull pin control updates from Linus Walleij:
"Here is the bulk of pin control changes for the v4.2 series: Quite a
lot of new SoC subdrivers and two new main drivers this time, apart
from that business as usual.
Details:
Core functionality:
- Enable exclusive pin ownership: it is possible to flag a pin
controller so that GPIO and other functions cannot use a single pin
simultaneously.
New drivers:
- NXP LPC18xx System Control Unit pin controller
- Imagination Pistachio SoC pin controller
New subdrivers:
- Freescale i.MX7d SoC
- Intel Sunrisepoint-H PCH
- Renesas PFC R8A7793
- Renesas PFC R8A7794
- Mediatek MT6397, MT8127
- SiRF Atlas 7
- Allwinner A33
- Qualcomm MSM8660
- Marvell Armada 395
- Rockchip RK3368
Cleanups:
- A big cleanup of the Marvell MVEBU driver rectifying it to
correspond to reality
- Drop platform device probing from the SH PFC driver, we are now a
DT only shop for SuperH
- Drop obsolte multi-platform check for SH PFC
- Various janitorial: constification, grammar etc
Improvements:
- The AT91 GPIO portions now supports the set_multiple() feature
- Split out SPI pins on the Xilinx Zynq
- Support DTs without specific function nodes in the i.MX driver"

Documentation/vm/unevictable-lru.txt: clarify MAP_LOCKED behavior
There is a very subtle difference between mmap()+mlock() vs mmap(MAP_LOCKED) semantic. The former one fails if the population of the area fails while the later one doesn't. This basically means that mmap(MAPLOCKED) areas might see major fault after mmap syscall returns which is not the case for mlock. mmap man page has already been altered but Documentation/vm/unevictable-lru.txt deserves a clarification as well.

watchdog: add watchdog_cpumask sysctl to assist nohz
Change the default behavior of watchdog so it only runs on the housekeeping cores when nohz_full is enabled at build and boot time. Allow modifying the set of cores the watchdog is currently running on with a new kernel.watchdog_cpumask sysctl. In the current system, the watchdog subsystem runs a periodic timer that schedules the watchdog kthread to run. However, nohz_full cores are designed to allow userspace application code running on those cores to have 100% access to the CPU. So the watchdog system prevents the nohz_full application code from being able to run the way it wants to, thus the motivation to suppress the watchdog on nohz_full cores, which this patchset provides by default. However, if we disable the watchdog globally, then the housekeeping cores can't benefit from the watchdog functionality. So we allow disabling it only on some cores. See Documentation/lockup-watchdogs.txt for more information.

arm64 updates for 4.2, mostly refactoring/clean-up:
- CPU ops and PSCI (Power State Coordination Interface) refactoring
following the merging of the arm64 ACPI support, together with
handling of Trusted (secure) OS instances
- Using fixmap for permanent FDT mapping, removing the initial dtb
placement requirements (within 512MB from the start of the kernel
image). This required moving the FDT self reservation out of the
memreserve processing
- Idmap (1:1 mapping used for MMU on/off) handling clean-up
- Removing flush_cache_all() - not safe on ARM unless the MMU is off.
Last stages of CPU power down/up are handled by firmware already
- "Alternatives" (run-time code patching) refactoring and support for
immediate branch patching, GICv3 CPU interface access
- User faults handling clean-up
And some fixes:
- Fix for VDSO building with broken ELF toolchains
- Fixing another case of init_mm.pgd usage for user mappings (during
ASID roll-over broadcasting)
- Fix for FPSIMD reloading after CPU hotplug
- Fix for missing syscall trace exit
- Workaround for .inst asm bug
- Compat fix for switching the user tls tpidr_el0 register

The bulk of the changes here is for x86. And for once it's not
for silicon that no one owns: these are really new features for
everyone.
* ARM: several features are in progress but missed the 4.2 deadline.
So here is just a smattering of bug fixes, plus enabling the VFIO
integration.
* s390: Some fixes/refactorings/optimizations, plus support for
2GB pages.
* x86: 1) host and guest support for marking kvmclock as a stable
scheduler clock. 2) support for write combining. 3) support for
system management mode, needed for secure boot in guests. 4) a bunch
of cleanups required for 2+3. 5) support for virtualized performance
counters on AMD; 6) legacy PCI device assignment is deprecated and
defaults to "n" in Kconfig; VFIO replaces it. On top of this there are
also bug fixes and eager FPU context loading for FPU-heavy guests.
* Common code: Support for multiple address spaces; for now it is
used only for x86 SMM but the s390 folks also have plans.
There are some x86 conflicts, one with the rc8 pull request and
the rest with Ingo's FPU rework.

IOMMU Updates for Linux v4.2
This time with bigger changes than usual:
* A new IOMMU driver for the ARM SMMUv3. This IOMMU is pretty
different from SMMUv1 and v2 in that it is configured through
in-memory structures and not through the MMIO register region.
The ARM SMMUv3 also supports IO demand paging for PCI devices
with PRI/PASID capabilities, but this is not implemented in
the driver yet.
* Lots of cleanups and device-tree support for the Exynos IOMMU
driver. This is part of the effort to bring Exynos DRM support
upstream.
* Introduction of default domains into the IOMMU core code. The
rationale behind this is to move functionalily out of the
IOMMU drivers to common code to get to a unified behavior
between different drivers.
The patches here introduce a default domain for iommu-groups
(isolation groups). A device will now always be attached to a
domain, either the default domain or another domain handled by
the device driver. The IOMMU drivers have to be modified to
make use of that feature. So long the AMD IOMMU driver is
converted, with others to follow.
* Patches for the Intel VT-d drvier to fix DMAR faults that
happen when a kdump kernel boots. When the kdump kernel boots
it re-initializes the IOMMU hardware, which destroys all
mappings from the crashed kernel. As this happens before
the endpoint devices are re-initialized, any in-flight DMA
causes a DMAR fault. These faults cause PCI master aborts,
which some devices can't handle properly and go into an
undefined state, so that the device driver in the kdump kernel
fails to initialize them and the dump fails.
This is now fixed by copying over the mapping structures (only
context tables and interrupt remapping tables) from the old
kernel and keep the old mappings in place until the device
driver of the new kernel takes over. This emulates the the
behavior without an IOMMU to the best degree possible.
* A couple of other small fixes and cleanups.

Broadcom STB SoCs (BCM7xxx), but now also found on BCM63xxx, iProc (e.g.,
Cygnus, BCM5301x), BCM3xxx, and more
* Begin factoring out BBT code so it can be shared between traditional
(parallel) NAND drivers and upcoming SPI NAND drivers (WIP)
