KVM fixes for 3.11
On the x86 side, there are some optimizations and documentation updates. The big ARM/KVM change for 3.11, support for AArch64, will come through Catalin Marinas's tree. s390 and PPC have misc cleanups and bugfixes. There is a conflict due to "s390/pgtable: fix ipte notify bit" having entered 3.10 through Martin Schwidefsky's s390 tree. This pull request has additional changes on top, so this tree's version is the correct one. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.13 (GNU/Linux) iQIcBAABAgAGBQJR0oU6AAoJEBvWZb6bTYbynnsP/RSUrrHrA8Wu1tqVfAKu+1y5 6OIihqZ9x11/YMaNofAfv86jqxFu0/j7CzMGphNdjzujqKI+Q1tGe7oiVCmKzoG+ UvSctWsz0lpllgBtnnrm5tcfmG6rrddhLtpA7m320+xCVx8KV5P4VfyHZEU+Ho8h ziPmb2mAQ65gBNX6nLHEJ3ITTgad6gt4NNbrKIYpyXuWZQJypzaRqT/vpc4md+Ed dCebMXsL1xgyb98EcnOdrWH1wV30MfucR7IpObOhXnnMKeeltqAQPvaOlKzZh4dK +QfxJfdRZVS0cepcxzx1Q2X3dgjoKQsHq1nlIyz3qu1vhtfaqBlixLZk0SguZ/R9 1S1YqucZiLRO57RD4q0Ak5oxwobu18ZoqJZ6nledNdWwDe8bz/W2wGAeVty19ky0 qstBdM9jnwXrc0qrVgZp3+s5dsx3NAm/KKZBoq4sXiDLd/yBzdEdWIVkIrU3X9wU 3X26wOmBxtsB7so/JR7ciTsQHelmLicnVeXohAEP9CjIJffB81xVXnXs0P0SYuiQ RzbSCwjPzET4JBOaHWT0Dhv0DTS/EaI97KzlN32US3Bn3WiLlS1oDCoPFoaLqd2K LxQMsXS8anAWxFvexfSuUpbJGPnKSidSQoQmJeMGBa9QhmZCht3IL16/Fb641ToN xBohzi49L9FDbpOnTYfz =1zpG -----END PGP SIGNATURE----- Merge tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm Pull KVM fixes from Paolo Bonzini: "On the x86 side, there are some optimizations and documentation updates.

spi: Updates for v3.11
A fairly quiet release for the SPI subsystem, the standout changes
being:
- Core support for implementing bits per word constraints implemented by
Stephen Warren, factoring some code out of drivers.
- Addition of polling mode support for the s3c64xx driver as some newer
Exynos systems have taken the unusual step of removing interrupt
support.
- Use of the in-IP FIFO and generic dmaengine support for the OMAP2
driver, providing improved performance.
- Conversion of the mpc512x driver to use the core message queue
infrastructure.
The nicest thing being that all the factoring out into common code leads
to a negative diffstat overall.

Pin control changes for the v3.11 kernel cycle:
- A large slew of improvements of the Genric pin configuration support, and deployment in four different platforms: Rockchip, Super-H PFC, ABx500 and TZ1090. Support BIAS_BUS_HOLD, get device tree parsing and debugfs support into shape. - We also have device tree support with generic naming conventions for the generic pin configuration. - Delete the unused and confusing direct pinconf API. Now state transitions is *the* way to control pins and multiplexing. - New drivers for Rockchip, TZ1090, and TZ1090 PDC. - Two pin control states related to power management are now handled in the device core: "sleep" and "idle", removing a lot of boilerplate code in drivers. We do not yet know if this is the final word for pin PM, but it already make things a lot easier to handle. - Handle sparse GPIO ranges passing a list of disparate pins, and utilize these in the new BayTrail (x86 Atom SoC) driver. - Make the sunxi (AllWinner) driver handle external interrupts. - Make it possible for pinctrl-single to handle the case where several pins are managed by a single register, and augment it to handle sleep modes. - Cleanups and improvements for the abx500 drivers. - Move Sirf pin control drivers to their own directory, support save/restore of context and add support for the SiRFatlas6 SoC. - PMU muxing for the Dove pinctrl driver. - Finalization and support for VF610 in the i.MX6 pinctrl driver. - Smoothen out various Exynos rough edges. - Generic cleanups of various kinds. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (GNU/Linux) iQIcBAABAgAGBQJR0Z07AAoJEEEQszewGV1zx+oP/j+bh39e1Fc8ySFNvpwLFFRb EbQZx21XsK+d4fUVYQJ1IBh3e5FTqkmvHarbO1aNttqyk7eN5P4EFb3dLExIX+81 6SJYtldH5ZdvLpJNvSXAX6fUjTD1CtBCDs5z5AvDQjqUArQ2tKlzJJgFXW8MSd3B 5hd7XdU5g30GbVzFwrPbVUZwRM12YVs/HACkP6uFqDjB8KX6nXpETlqeeFW+ApvW RPT7iN/CsFls7gl6mHsPvScdfXar0ilZfu0hTf3EmhlVK1/iPOV6aqAF9z4j2Yxf ICL/x3phJ0Q7yNeZslif0KN3iJnrRGbdNvBi6wim35Ds5Uf3lY2SAhSvxNmkjT8n DB9oBTvQzr5OEv8fstWJAT+BWIdZ6Z91IqJ5Gy40A91oVUU9NDDBR3ur2gIneEUz 51kOUhucCzpiht5A/7djAx6MYYOEUwjGNzjOs7tGcxCxz4+Rb2DbAXZ3Cew45ddh 1QsfL3588A0DTp7ccw7f4QwYveX/cquzia/MD8AtdrUSYFEPfkexEo540/VqMl8j aMJ8Uuca9GSnyXDk+ziwkzLg2DjTw+p+6IygNr2GLrXFH2LTAKRpz/SidyLArDsw 0sTFan0sdU3497rHX5Xc8yCyDY4sXCdQm3/er+TE+Z7V2dS99GuEysCAInIdvM1I Wupqaxw4A25YSmbRFVpR =EbAf -----END PGP SIGNATURE----- Merge tag 'pinctrl-for-v3.11-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl Pull pin control changes from Linus Walleij: - A large slew of improvements of the Genric pin configuration support, and deployment in four different platforms: Rockchip, Super-H PFC, ABx500 and TZ1090.

We do not yet know if this is the final word for pin PM, but it already make things a lot easier to handle. - Handle sparse GPIO ranges passing a list of disparate pins, and utilize these in the new BayTrail (x86 Atom SoC) driver. - Make the sunxi (AllWinner) driver handle external interrupts. - Make it possible for pinctrl-single to handle the case where several pins are managed by a single register, and augment it to handle sleep modes. - Cleanups and improvements for the abx500 drivers. - Move Sirf pin control drivers to their own directory, support save/restore of context and add support for the SiRFatlas6 SoC. - PMU muxing for the Dove pinctrl driver. - Finalization and support for VF610 in the i.MX6 pinctrl driver. - Smoothen out various Exynos rough edges. - Generic cleanups of various kinds. * tag 'pinctrl-for-v3.11-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl: (82 commits) pinctrl: vt8500: wmt: remove redundant dev_err call in wmt_pinctrl_probe() pinctrl: remove bindings for pinconf options needing more thought pinctrl: remove slew-rate parameter from tz1090 pinctrl: set unit for debounce time pinconfig to usec pinctrl: more clarifications for generic pull configs pinctrl: rip out the direct pinconf API pinctrl-tz1090-pdc: add TZ1090 PDC pinctrl driver pinctrl-tz1090: add TZ1090 pinctrl driver pinctrl: samsung: Staticize drvdata_list pinctrl: rockchip: Add missing irq_gc_unlock() call before return error pinctrl: abx500: rework error path pinctrl: abx500: suppress hardcoded value pinctrl: abx500: factorize code pinctrl: abx500: fix abx500_gpio_get() pinctrl: abx500: fix abx500_pin_config_set() pinctrl: abx500: Add device tree support sh-pfc: Guard DT parsing with #ifdef CONFIG_OF pinctrl: add Intel BayTrail GPIO/pinctrl support pinctrl: fix pinconf_ops::pin_config_dbg_parse_modify kerneldoc pinctrl: Staticize local symbols ...

regmap: Updates for v3.11
A small but useful set of regmap updates this time around:
- An abstraction for bitfields within a register map contributed by
Srinivas Kandagatla, allowing drivers to cope more easily when
hardware designers randomly move things about (mainly when talking
to things like system controllers).
- Changes from Lars-Peter Clausen to allow the MMIO regmap to be used from
hard IRQ context.
- Small improvements to the cache infrastructure and performance,
including a default cache sync operation so now all regmaps can sync
easily.
There's also a pinctrl driver making use of the new bitfield API, merged
here for dependency reasons. There will be a simple add/add conflict
with the pinctrl tree as a result.

ARC changes for 3.11
Highlights of changes:
-Continuation of ARC MM changes from 3.10 including
zero page optimization;
Setting pagecache pages dirty by default;
Non executable stack by default;
Reducing dcache flushes for aliasing VIPT config
-Long overdue rework of pt_regs machinery - removing the unused word gutters
and adding ECR register to baseline (helps cleanup lot of low level code)
-Support for ARC gcc 4.8
-Few other preventive fixes, cosmetics, usage of Kconfig helper..
The diffstat is larger than normal primarily because of arcregs.h header split
as well as beautification of macros in entry.h

Merge branch 'for-linus' of git://git.linaro.org/people/rmk/linux-arm
Pull ARM updates from Russell King:
"This contains the usual updates from other people (listed below) and
the usual random muddle of miscellaneous ARM updates which cover some
low priority bug fixes and performance improvements.
I've started to put the pull request wording into the merge commits,
which are:
- NoMMU stuff:
This includes the following series sent earlier to the list:
- nommu-fixes
- R7 Support
- MPU support
I've left out the ARCH_MULTIPLATFORM/!MMU stuff that Arnd and I
were discussing today until we've reached a conclusion/that's had
some more review.
This is rebased (and re-tested) on your devel-stable branch because
otherwise there were going to be conflicts with Uwe's V7M work now
that you've merged that. I've included the fix for limiting MPU to
CPU_V7.
- Huge page support
These changes bring both HugeTLB support and Transparent HugePage
(THP) support to ARM. Only long descriptors (LPAE) are supported
in this series.
The code has been tested on an Arndale board (Exynos 5250).
- LPAE updates
Please pull these miscellaneous LPAE fixes I've been collecting for
a while now for 3.11. They've been tested and reviewed by quite a
few people, and most of the patches are pretty trivial. -- Will Deacon.
- arch_timer cleanups
Please pull these arch_timer cleanups I've been holding onto for a
while. They're the same as my last posting, but have been rebased
to v3.10-rc3.
- mpidr linearisation (multiprocessor id register - identifies which
CPU number we are in the system)
This patch series that implements MPIDR linearization through a
simple hashing algorithm and updates current cpu_{suspend}/{resume}
code to use the newly created hash structures to retrieve context
pointers. It represents a stepping stone for the implementation of
power management code on forthcoming multi-cluster ARM systems.
It has been tested on TC2 (dual cluster A15xA7 system), iMX6q,
OMAP4 and Tegra, with processors hitting low-power states requiring
warm-boot resume through the cpu_resume code path"

vfs: export lseek_execute() to modules
For those file systems(btrfs/ext4/ocfs2/tmpfs) that support SEEK_DATA/SEEK_HOLE functions, we end up handling the similar matter in lseek_execute() to update the current file offset to the desired offset if it is valid, ceph also does the simliar things at ceph_llseek(). To reduce the duplications, this patch make lseek_execute() public accessible so that we can call it directly from the underlying file systems. Thanks Dave Chinner for this suggestion.

Merge branch 'for-3.11-cpuset' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup
Pull cpuset changes from Tejun Heo:
"cpuset has always been rather odd about its configurations - a cgroup
right after creation didn't allow any task executions before
configuration, changing configuration in the parent modifies the
descendants irreversibly and so on. These behaviors are inherently
nasty and almost hostile against sharing the hierarchy with other
controllers making it very difficult to use in unified hierarchy.
Li is currently in the process of updating the behaviors for
__DEVEL__sane_behavior which is the bulk of changes in this pull
request. It isn't complete yet and the behaviors will change further
but all changes are gated behind sane_behavior. In the process, the
rather hairy work-item punting which was used to work around the
limitations of cgroup descendant iterator was simplified."

Pull cgroup changes from Tejun Heo:
"This pull request contains the following changes.
- cgroup_subsys_state (css) reference counting has been converted to
percpu-ref. css is what each resource controller embeds into its
own control structure and perform reference count against. It may
be used in hot paths of various subsystems and is similar to module
refcnt in that aspect. For example, block-cgroup's css refcnting
was showing up a lot in Mikulaus's device-mapper scalability work
and this should alleviate it.
- cgroup subtree iterator has been updated so that RCU read lock can
be released after grabbing reference. This allows simplifying its
users which requires blocking which used to build iteration list
under RCU read lock and then traverse it outside. This pull
request contains simplification of cgroup core and device-cgroup.
A separate pull request will update cpuset.
- Fixes for various bugs including corner race conditions and RCU
usage bugs.
- A lot of cleanups and some prepartory work for the planned unified
hierarchy support."

Pull workqueue changes from Tejun Heo: "Surprisingly, Lai and I didn't break too many things implementing custom pools and stuff last time around and there aren't any follow-up changes necessary at this point. The only change in this pull request is Viresh's patches to make some per-cpu workqueues to behave as unbound workqueues dependent on a boot param whose default can be configured via a config option. This leads to higher processing overhead / lower bandwidth as more work items are bounced across CPUs; however, it can lead to noticeable powersave in certain configurations - ~10% w/ idlish constant workload on a big.LITTLE configuration according to Viresh. This is because per-cpu workqueues interfere with how the scheduler perceives whether or not each CPU is idle by forcing pinned tasks on them, which makes the scheduler's power-aware scheduling decisions less effective. Its effectiveness is likely less pronounced on homogenous configurations and this type of optimization can probably be made automatic; however, the changes are pretty minimal and the affected workqueues are clearly marked, so it's an easy gain for some configurations for the time being with pretty unintrusive changes." * 'for-3.11' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/wq: fbcon: queue work on power efficient wq block: queue work on power efficient wq PHYLIB: queue work on system_power_efficient_wq workqueue: Add system wide power_efficient workqueues workqueues: Introduce new flag WQ_POWER_EFFICIENT for power oriented workqueues |

Merge branch 'sched-mm-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull voluntary preemption fixes from Ingo Molnar:
"This tree contains a speedup which is achieved through better
might_sleep()/might_fault() preemption point annotations for uaccess
functions, by Michael S Tsirkin:
1. The only reason uaccess routines might sleep is if they fault.
Make this explicit for all architectures.
2. A voluntary preemption point in uaccess functions means compiler
can't inline them efficiently, this breaks assumptions that they
are very fast and small that e.g. net code seems to make. Remove
this preemption point so behaviour matches with what callers
assume.
3. Accesses (e.g through socket ops) to kernel memory with KERNEL_DS
like net/sunrpc does will never sleep. Remove an unconditinal
might_sleep() in the might_fault() inline in kernel.h (used when
PROVE_LOCKING is not set).
4. Accesses with pagefault_disable() return EFAULT but won't cause
caller to sleep. Check for that and thus avoid might_sleep() when
PROVE_LOCKING is set.
These changes offer a nice speedup for CONFIG_PREEMPT_VOLUNTARY=y
kernels, here's a network bandwidth measurement between a virtual
machine and the host:
before:
incoming: 7122.77 Mb/s
outgoing: 8480.37 Mb/s
after:
incoming: 8619.24 Mb/s [ +21.0% ]
outgoing: 9455.42 Mb/s [ +11.5% ]

Wound/wait mutexes are used when other multiple lock acquisitions of a
similar type can be done in an arbitrary order. The deadlock handling
used here is called wait/wound in the RDBMS literature: The older
tasks waits until it can acquire the contended lock. The younger
tasks needs to back off and drop all the locks it is currently
holding, ie the younger task is wounded.
See this LWN.net description of W/W mutexes:

ARM SoC late changes
These are changes that arrived a little late before the merge
window or that have multiple dependencies on previous branches
so they did not fit into one of the earlier ones. There
are 10 branches merged here, a total of 39 non-merge commits.
Contents are a mixed bag for the above reasons:
* Two new SoC platforms: ST microelectronics stixxxx and
the TI 'Nspire' graphing calculator. These should have
been in the 'soc' branch but were a little late
* Support for the Exynos 5420 variant in mach-exynos,
which is based on the other exynos branches to avoid
conflicts.
* Various small changes for sh-mobile, ux500 and davinci
* Common clk support for MSM
Conflicts:
* In Kconfig.debug, various additions trivially conflict,
the list should be kept in alphabetical order when
resolving.

ARM SoC driver specific changes
These changes are all driver specific and cross over between arm-soc contents and some other subsystem, in these cases cpufreq, crypto, dma, pinctrl, mailbox and usb, and the subsystem owners agreed to have these changes merged through arm-soc. As we proceed to untangle the dependencies between platform code and driver code, the amount of changes in this category is fortunately shrinking, for 3.11 we have 16 branches here and 101 non-merge changesets, the majority of which are for the stedma40 dma engine driver used in the ux500 platform. Cleaning up that code touches multiple subsystems, but gets rid of the dependency in the end. The mailbox code moved out from mach-omap2 to drivers/mailbox is an intermediate step and is still omap specific at the moment. Patches exist to generalize the subsystem and add other drivers with the same API, but those did not make it for 3.11. Conflicts: * In cpu-db8500.c results from the removal of the u8500_of_init_devices function in combination with the split of u8500_auxdata_lookup. * In arch/arm/mach-omap2/devices.c, the includes got reshuffled. we need to keep linux/wl12xx.h and linux/platform_data/mailbox-omap.h. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) iQIVAwUAUdLnomCrR//JCVInAQJI/A/9FydsQa9sdnzLFgcdX5BeRRwkXLfDifCM zDTfUBo+LriKOs7QHblmDg1MnY1UMB2IfrdHD0FsjK7WbZ/91EMAGDPYcI7Fu4+u pGStxwWi2v+oCT1jjeOkCPT7hdCqogsSpybYq8itSb+zdvdOi6U35dWEKz8xGqz4 vTL9gTZbJP0kowkjIcaryk7FIj7BTIvMCW8n55JZEkDe0BuSJGYn5c3Mntut12ZK 5xM2PeNe2sd3dIdA6XbM2ye/XmYa8xY8Qu4/ijxfH1gnJLvz9Unp96nRXpEbIeMb BH2Sro8dxsMCaweIQhSRKGnUWMYO/Rh7/+5EqzJ163Ezthx9nvHXJY2ndWuD7uM1 IcGrMxLtqP22TEMtZAVEATDp/5ymxEo5GM+eayUojQDn213wOJjRs5xz5IBsH4KM 8CM/gpadWmLjWku72yEV4lryLcdS0NVQzpTnEbILEGOU4u7qJtxRAp7x7tWBtFg8 4m/eWcSVk/U2SYbXmQHsfukuWgKY0cnZbctPcdnaqXwTP7toJEAK3gxoMtWh49Jq 2M2PVFyFejaaq5b/71wAJ7ePYw56H0N/F3RsGpPE55AY15++gSoQ+3t2Si68hDw8 NtyJMkQYpTvtqJbHXWpQQ3Zfs7pDBe01WDV7i+m4JTNggxUDaO/t1Fqp+fEksm4J r+luEf5Gcgk= =mJsI -----END PGP SIGNATURE----- Merge tag 'drivers-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC driver specific changes from Arnd Bergmann: "These changes are all driver specific and cross over between arm-soc contents and some other subsystem, in these cases cpufreq, crypto, dma, pinctrl, mailbox and usb, and the subsystem owners agreed to have these changes merged through arm-soc.
