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.

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"

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

Pull WW mutex support from Ingo Molnar:
"This tree adds support for wound/wait style locks, which the graphics
guys would like to make use of in the TTM graphics subsystem.
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:
https://lwn.net/Articles/548909/
The comments there outline specific usecases for this facility (which
have already been implemented for the DRM tree).

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.

ARM SoC device tree changes
These changes from 30 individual branches for the most part update device tree files, but there are also a few source code changes that have crept in this time, usually in order to atomically move over a driver from using hardcoded data to DT probing. A number of platforms change their DT files to use the C preprocessor, which is causing a bit of churn, but that is hopefully only this once. There are a few conflicts with the other branches unfortunately: * in exynos5440.dtsi and kirkwood-6281.dtsi, device nodes are added from multiple branches. Need to be careful to have the right set of closing braces as git gets this one wrong. * In kirkwood.dtsi, one 'ranges' line got split into two lines, while another line got added. Order of the lines does not matter. * in sama5d3.dtsi, some cleanup was merged the wrong way, causing a bogus conflict. We want the 'dmas' and 'dma-names' properties to get added here. * Two lines got removed independently in arch/arm/mach-mxs/mach-mxs.c * Contents get added independently in arch/arm/mach-omap2/cclock33xx_data.c -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) iQIVAwUAUdLnpGCrR//JCVInAQI50RAAsXbH1SGvjKJemXhRkFloPDYpCbgdDUFr ChUbjNV1xsY/jaNCfMa5/Qo7lgz/Ot7BpJef9fZn7ret+dc7nchqe/4iIkAokAUh E4ao9D1dP5aAA0ihdbSQHCZtR/0SUR81h6BoOVuo/1mvEiBaFbWAeYe8/6LJd9II OU1w9bDmjfZWYFUXs+j2VF76ueZQ+kz69XDKZUGtkqN76m1AL8lGDurj5jxvyllF VJns8d9q2nr2q9PferfajK6rkOIPaTpwKblxZHUgobCyOitZaiZM0NgF733TsNM6 HXmhDhkcn7T81+SiHVfigJ/nxo9UgU4zNJCODF3WZIwGIj3FbxvCOpdCYi2NhCO8 oLcgDk57tpoKpB3gvAmYVQHP9FIepFa/WAWyPIADA7PkpYrwgc4v+cLEHXpd8SRv viLLIa5QuNdMeaK+Md9OKmKZFd7uFD9jiMtmdm6IpEVDDjMgoteb2XSoEtNebmtY MfbW4okn118a2dFKKaPTKcXVW/a5FRp2JGfB0A58RQHaJWj3JsY1bFn/xWPEpTOA IWB/HHMln0LYTL2AXN9HcaL1jnGI1Wq5eWBurX+cXQ/ij1A6jfoRKYglx7AQqOHj iWcGYtKLLJCgiWFnLSwcljZhfoYr0/z7rhns6yo7/vhN0riy+M84OgN4HbAmUzc1 Bgy9PnJTNo8= =8PtJ -----END PGP SIGNATURE----- Merge tag 'dt-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC device tree changes from Arnd Bergmann: "These changes from 30 individual branches for the most part update device tree files, but there are also a few source code changes that have crept in this time, usually in order to atomically move over a driver from using hardcoded data to DT probing.

ARM SoC board specific changes
These are 18 branches on 9 platforms with board specific changes, mostly for defconfig files, but nothing really exciting in here. Since the shmobile platform still uses board files for some of the newer machines, we get a few changes there as the result of drivers getting enabled for those boards. This causes some conflicts with contents getting added from multiple branches in sh-mobile specific files. Renesas is putting a lot of work into migrating to device-tree based setup, which will make all those files obsolete in the future and avoid both the conflicts and the need to have these files in the first place. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) iQIVAwUAUdLnmmCrR//JCVInAQKNuxAAxXpBslUGRpI8O28KHA3EeL+9HR5wBoKo K6q6fQlAv9dcGJOx7fkyHU4UfE1kV+M6l4R9BM8VcjflQjCnG4GrQo8qgJNY14nf OpQKSIHEtdBHzFpHEIxogByR1i05hL8nrm21TElgi/aYlDwKbXnApY23ubApPif4 oXmES9ppXvnz1D7bCE7PaZf+TIgufpPFkioQYcV93nD0x5tYu1mZn2xSfYDekAyU mUe1p2oX+77U0lohVQCo1H/ZOJBdoAN1U//2QCiL8YKJitQf/vOVs3QtHEUywIiU CyUaDhfM7sX4QKBWzwjxoVOcT6QC/qhaaqaases0gjgjepKaSqUTZMBdLI7oyF3o 2ExYv8BMGilbIyNUYoxeoqz9zA3IQ7wDxaBh3G1JY9k0/BhKmsEwtGYkSJPdOgpt XyX7N/xKzy0lTWf1N4eSWUiccfXdVjLFf3Jp2xA7e/KJfzFAF/RJXdGiV2Kzdr7m mZ7ESYRk+S3ENgpI/QI4C6kQ7EBynQjhn5t2+iK9k4gKNspNZ3TjLCQif0v0xE3H IIsaSqLBuj9IZ1r13fpQJZIyTr+dHsx2s6QQBFXYzeQ/cjfSRGZP4FmYyweGctfR Hh1AAshrOAwNl4ZdXgIT08JKtBocaGFUtt4syvPfAFYoojMN58xg5EG4FYtKpKHp xU6w43o6KnQ= =7bgc -----END PGP SIGNATURE----- Merge tag 'boards-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC board specific changes from Arnd Bergmann: "These are 18 branches on 9 platforms with board specific changes, mostly for defconfig files, but nothing really exciting in here.

ARM SoC specific changes
These changes are all to SoC-specific code, a total of 33 branches on 17 platforms were pulled into this. Like last time, Renesas sh-mobile is now the platform with the most changes, followed by OMAP and EXYNOS. Two new platforms, TI Keystone and Rockchips RK3xxx are added in this branch, both containing almost no platform specific code at all, since they are using generic subsystem interfaces for clocks, pinctrl, interrupts etc. The device drivers are getting merged through the respective subsystem maintainer trees. One more SoC (u300) is now multiplatform capable and several others (shmobile, exynos, msm, integrator, kirkwood, clps711x) are moving towards that goal with this series but need more work. Also noteworthy is the work on PCI here, which is traditionally part of the SoC specific code.

ARM SoC cleanups
This contains cleanups as preparation for other branches adding new features, we pulled 16 branches for 9 platforms into this one. Most notable here is the removal of support for ATAGS based OMAP4 systems. Since all OMAP4 machines are fully functional with DT based booting in 3.10, we can remove a lot of code here. Also noteworthy is Maxime Ripard's cleanup of the machine descriptors, which means we need no machine descriptors in a lot more cases and can boot additional machines by just having the respective device drivers enabled. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) iQIVAwUAUdLnoGCrR//JCVInAQL5bw/+OZeE60sBJxgDAf9XEYls9t5cnLY963uE izgsyLKwwAi21Xbg/0vgGZLbpdfyd2IJa+bWXhxVTLFI43Hb0D2x1hYyMzy/fFWj gmqQ4dLYawYj+1sOirTPWDquR31mavofmMF2HVk23S6NWmNIjPk1+7Wgd46Y4vNX 7T6j4cg9HPrxQ37a6ucOuEX6+rqmFe2Q+v7qcsXkwxkVxgIC8V4MgHJmt8gGMRvB HHrY1kPBHlMJm07fLngilAfpa8G91fmgKxSfugeClyKotj7lHxno/lh/+oxMGvaJ J9memdfbYISLSvDLeH6Rib/zaC7VnSij9QtZmFtToiJ6qVVZiLFd2dpP+ccpaMGb YEvm58ayajAvb0wZMueoeKs9yW0UWCdXdkzKbhuWrwmPDjKSb9f9t1u3ons8vl+2 dOwlTex9/ijsxu1qTHMm4/EVg+NR/AwVVwiBRG9sYnfxSHkgXxPW5TF7T4d1H71v WZkXWsJKIUDQgk+2nnE4J9TvFlPyaV09yFYyiY/+DWAs9DUus8cf37nt2Wz6H1l6 THQcQDcZsPLZsSIEdzUrchdLKDZHzhkb3i8pae7TC6CySiOzj/yX2zbh9Ot538WG 2C7qzAVtyMVuAdFh0caIu0iVXqjsnJLAZGImLZQySR00aq34uXh7MsHepnhAI10q EQ1vILi4mU4= =XDJs -----END PGP SIGNATURE----- Merge tag 'cleanup-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC cleanups from Arnd Bergmann: "This contains cleanups as preparation for other branches adding new features, we pulled 16 branches for 9 platforms into this one.

s390/dasd: Fail all requests when DASD_FLAG_ABORTIO is set
Whenever a DASD request encounters a timeout we might need to abort all outstanding requests on this or even other devices. This is especially useful if one wants to fail all devices on one side of a RAID10 configuration, even though only one device exhibited an error. To handle this I've introduced a new device flag DASD_FLAG_ABORTIO. This flag is evaluated in __dasd_process_request_queue() and will invoke blk_abort_request() for all outstanding requests with DASD_CQR_FLAGS_FAILFAST set. This will cause any of these requests to be aborted immediately if the blk_timeout function is activated. The DASD_FLAG_ABORTIO is also evaluated in __dasd_process_request_queue to abort all new request which would have the DASD_CQR_FLAGS_FAILFAST bit set. The flag can be set with the new ioctls 'BIODASDABORTIO' and removed with 'BIODASDALLOWIO'.

KVM: PPC: Ignore PIR writes
While technically it's legal to write to PIR and have the identifier changed, we don't implement logic to do so because we simply expose vcpu_id to the guest. So instead, let's ignore writes to PIR. This ensures that we don't inject faults into the guest for something the guest is allowed to do. While at it, we cross our fingers hoping that it also doesn't mind that we broke its PIR read values.
