c798360cd1 Merge branch 'for-3.18' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/percpu 
Pull percpu updates from Tejun Heo:
 "A lot of activities on percpu front.  Notable changes are...

   - percpu allocator now can take @gfp.  If @gfp doesn't contain
     GFP_KERNEL, it tries to allocate from what's already available to
     the allocator and a work item tries to keep the reserve around
     certain level so that these atomic allocations usually succeed.

     This will replace the ad-hoc percpu memory pool used by
     blk-throttle and also be used by the planned blkcg support for
     writeback IOs.

     Please note that I noticed a bug in how @gfp is interpreted while
     preparing this pull request and applied the fix 6ae833c7fe
     ("percpu: fix how @gfp is interpreted by the percpu allocator")
     just now.

   - percpu_ref now uses longs for percpu and global counters instead of
     ints.  It leads to more sparse packing of the percpu counters on
     64bit machines but the overhead should be negligible and this
     allows using percpu_ref for refcnting pages and in-memory objects
     directly.

   - The switching between percpu and single counter modes of a
     percpu_ref is made independent of putting the base ref and a
     percpu_ref can now optionally be initialized in single or killed
     mode.  This allows avoiding percpu shutdown latency for cases where
     the refcounted objects may be synchronously created and destroyed
     in rapid succession with only a fraction of them reaching fully
     operational status (SCSI probing does this when combined with
     blk-mq support).  It's also planned to be used to implement forced
     single mode to detect underflow more timely for debugging.

  There's a separate branch percpu/for-3.18-consistent-ops which cleans
  up the duplicate percpu accessors.  That branch causes a number of
  conflicts with s390 and other trees.  I'll send a separate pull
  request w/ resolutions once other branches are merged"

Pull libata update from Tejun Heo:
 "AHCI is getting per-port irq handling and locks for better
  scalability.  The gain is not huge but measureable with multiple high
  iops devices connected to the same host; however, the value of
  threaded IRQ handling seems negligible for AHCI and it likely will
  revert to non-threaded handling soon.

  Another noteworthy change is George Spelvin's "libata: Un-break ATA
  blacklist".  During 3.17 devel cycle, the libata blacklist glob
  matching got generalized and rewritten; unfortunately, the patch
  forgot to swap arguments to match the new match function and ended up
  breaking blacklist matching completely.  It got noticed only a couple
  days ago so it couldn't make for-3.17-fixes either.  :(

  Other than the above two, nothing too interesting - the usual cleanup
  churns and device-specific changes"

cd2567b685 m68k: call find_vma with the mmap_sem held in sys_cacheflush() 
Performing vma lookups without taking the mm->mmap_sem is asking for
trouble.  While doing the search, the vma in question can be modified or
even removed before returning to the caller.  Take the lock (shared) in
order to avoid races while iterating through the vmacache and/or rbtree.
In addition, this guarantees that the address space will remain intact
during the CPU flushing.

bd951303be arm: mm: introduce special ptes for LPAE 
We need a mechanism to tag ptes as being special, this indicates that no
attempt should be made to access the underlying struct page * associated
with the pte.  This is used by the fast_gup when operating on ptes as it
has no means to access VMAs (that also contain this information)
locklessly.

The L_PTE_SPECIAL bit is already allocated for LPAE, this patch modifies
pte_special and pte_mkspecial to make use of it, and defines
__HAVE_ARCH_PTE_SPECIAL.

This patch also excludes special ptes from the icache/dcache sync logic.

513510ddba common: dma-mapping: introduce common remapping functions 
For architectures without coherent DMA, memory for DMA may need to be
remapped with coherent attributes.  Factor out the the remapping code from
arm and put it in a common location to reduce code duplication.

As part of this, the arm APIs are now migrated away from
ioremap_page_range to the common APIs which use map_vm_area for remapping.
 This should be an equivalent change and using map_vm_area is more correct
as ioremap_page_range is intended to bring in io addresses into the cpu
space and not regular kernel managed memory.

6a33979d5b mm: remove misleading ARCH_USES_NUMA_PROT_NONE 
ARCH_USES_NUMA_PROT_NONE was defined for architectures that implemented
_PAGE_NUMA using _PROT_NONE.  This saved using an additional PTE bit and
relied on the fact that PROT_NONE vmas were skipped by the NUMA hinting
fault scanner.  This was found to be conceptually confusing with a lot of
implicit assumptions and it was asked that an alternative be found.

Commit c46a7c81 "x86: define _PAGE_NUMA by reusing software bits on the
PMD and PTE levels" redefined _PAGE_NUMA on x86 to be one of the swap PTE
bits and shrunk the maximum possible swap size but it did not go far
enough.  There are no architectures that reuse _PROT_NONE as _PROT_NUMA
but the relics still exist.

This patch removes ARCH_USES_NUMA_PROT_NONE and removes some unnecessary
duplication in powerpc vs the generic implementation by defining the types
the core NUMA helpers expected to exist from x86 with their ppc64
equivalent.  This necessitated that a PTE bit mask be created that
identified the bits that distinguish present from NUMA pte entries but it
is expected this will only differ between arches based on _PAGE_PROTNONE.
The naming for the generic helpers was taken from x86 originally but ppc64
has types that are equivalent for the purposes of the helper so they are
mapped instead of duplicating code.

b528392669 ACPI and power management updates for 3.18-rc1 
- Rework the handling of wakeup IRQs by the IRQ core such that
    all of them will be switched over to "wakeup" mode in
    suspend_device_irqs() and in that mode the first interrupt
    will abort system suspend in progress or wake up the system
    if already in suspend-to-idle (or equivalent) without executing
    any interrupt handlers.  Among other things that eliminates the
    wakeup-related motivation to use the IRQF_NO_SUSPEND interrupt
    flag with interrupts which don't really need it and should not
    use it (Thomas Gleixner and Rafael J Wysocki).
 
  - Switch over ACPI to handling wakeup interrupts with the help
    of the new mechanism introduced by the above IRQ core rework
    (Rafael J Wysocki).
 
  - Rework the core generic PM domains code to eliminate code that's
    not used, add DT support and add a generic mechanism by which
    devices can be added to PM domains automatically during
    enumeration (Ulf Hansson, Geert Uytterhoeven and Tomasz Figa).
 
  - Add debugfs-based mechanics for debugging generic PM domains
    (Maciej Matraszek).
 
  - ACPICA update to upstream version 20140828.  Included are updates
    related to the SRAT and GTDT tables and the _PSx methods are in
    the METHOD_NAME list now (Bob Moore and Hanjun Guo).
 
  - Add _OSI("Darwin") support to the ACPI core (unfortunately, that
    can't really be done in a straightforward way) to prevent
    Thunderbolt from being turned off on Apple systems after boot
    (or after resume from system suspend) and rework the ACPI Smart
    Battery Subsystem (SBS) driver to work correctly with Apple
    platforms (Matthew Garrett and Andreas Noever).
 
  - ACPI LPSS (Low-Power Subsystem) driver update cleaning up the
    code, adding support for 133MHz I2C source clock on Intel Baytrail
    to it and making it avoid using UART RTS override with Auto Flow
    Control (Heikki Krogerus).
 
  - ACPI backlight updates removing the video_set_use_native_backlight
    quirk which is not necessary any more, making the code check the
    list of output devices returned by the _DOD method to avoid
    creating acpi_video interfaces that won't work and adding a quirk
    for Lenovo Ideapad Z570 (Hans de Goede, Aaron Lu and Stepan Bujnak).
 
  - New Win8 ACPI OSI quirks for some Dell laptops (Edward Lin).
 
  - Assorted ACPI code cleanups (Fabian Frederick, Rasmus Villemoes,
    Sudip Mukherjee, Yijing Wang, and Zhang Rui).
 
  - cpufreq core updates and cleanups (Viresh Kumar, Preeti U Murthy,
    Rasmus Villemoes).
 
  - cpufreq driver updates: cpufreq-cpu0/cpufreq-dt (driver name
    change among other things), ppc-corenet, powernv (Viresh Kumar,
    Preeti U Murthy, Shilpasri G Bhat, Lucas Stach).
 
  - cpuidle support for DT-based idle states infrastructure, new
    ARM64 cpuidle driver, cpuidle core cleanups (Lorenzo Pieralisi,
    Rasmus Villemoes).
 
  - ARM big.LITTLE cpuidle driver updates: support for DT-based
    initialization and Exynos5800 compatible string (Lorenzo Pieralisi,
    Kevin Hilman).
 
  - Rework of the test_suspend kernel command line argument and
    a new trace event for console resume (Srinivas Pandruvada,
    Todd E Brandt).
 
  - Second attempt to optimize swsusp_free() (hibernation core) to
    make it avoid going through all PFNs which may be way too slow on
    some systems (Joerg Roedel).
 
  - devfreq updates (Paul Bolle, Punit Agrawal, Ãrjan Eide).
 
  - rockchip-io Adaptive Voltage Scaling (AVS) driver and AVS
    entry update in MAINTAINERS (Heiko Stübner, Kevin Hilman).
 
  - PM core fix related to clock management (Geert Uytterhoeven).
 
  - PM core's sysfs code cleanup (Johannes Berg).

Merge tag 'pm+acpi-3.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull ACPI and power management updates from Rafael Wysocki:
 "Features-wise, to me the most important this time is a rework of
  wakeup interrupts handling in the core that makes them work
  consistently across all of the available sleep states, including
  suspend-to-idle.  Many thanks to Thomas Gleixner for his help with
  this work.

  Second is an update of the generic PM domains code that has been in
  need of some care for quite a while.  Unused code is being removed, DT
  support is being added and domains are now going to be attached to
  devices in bus type code in analogy with the ACPI PM domain.  The
  majority of work here was done by Ulf Hansson who also has been the
  most active developer this time.

  Apart from this we have a traditional ACPICA update, this time to
  upstream version 20140828 and a few ACPI wakeup interrupts handling
  patches on top of the general rework mentioned above.  There also are
  several cpufreq commits including renaming the cpufreq-cpu0 driver to
  cpufreq-dt, as this is what implements generic DT-based cpufreq
  support, and a new DT-based idle states infrastructure for cpuidle.

  In addition to that, the ACPI LPSS driver is updated, ACPI support for
  Apple machines is improved, a few bugs are fixed and a few cleanups
  are made all over.

  Finally, the Adaptive Voltage Scaling (AVS) subsystem now has a tree
  maintained by Kevin Hilman that will be merged through the PM tree.

  Numbers-wise, the generic PM domains update takes the lead this time
  with 32 non-merge commits, second is cpufreq (15 commits) and the 3rd
  place goes to the wakeup interrupts handling rework (13 commits).

  Specifics:

   - Rework the handling of wakeup IRQs by the IRQ core such that all of
     them will be switched over to "wakeup" mode in suspend_device_irqs()
     and in that mode the first interrupt will abort system suspend in

ea584595fc This is the bulk of GPIO changes for the v3.18 development 
cycle:
 
 - Increase the default ARCH_NR_GPIO from 256 to 512. This
   was done to avoid having a custom <asm/gpio.h> header for
   the x86 architecture - GPIO is custom and complicated
   enough as it is already! We want to move to a radix to
   store the descriptors going forward, and finally get rid
   of this fixed array size altogether.
 
 - Endgame patching of the gpio_remove() semantics initiated
   by Abdoulaye Berthe. It is not accepted by the system that
   the removal of a GPIO chip fails during e.g. reboot or
   shutdown, and therefore the return value has now painfully
   been refactored away. For special cases like GPIO expanders
   on a hot-pluggable bus like USB, we may later add some
   gpiochip_try_remove() call, but for the cases we have now,
   return values are moot.
 
 - Some incremental refactoring of the gpiolib core and ACPI
   GPIO library for more descriptor usage.
 
 - Refactor the chained IRQ handler set-up method to handle
   also threaded, nested interrupts and set up the parent IRQ
   correctly. Switch STMPE and TC3589x drivers to use this
   registration method.
 
 - Add a .irq_not_threaded flag to the struct gpio_chip, so
   that also GPIO expanders that block but are still not
   using threaded IRQ handlers.
 
 - New drivers for the ARM64 X-Gene SoC GPIO controller.
 
 - The syscon GPIO driver has been improved to handle the
   "DSP GPIO" found on the TI Keystone 2 SoC:s.
 
 - ADNP driver switched to use gpiolib irqchip helpers.
 
 - Refactor the DWAPB driver to support being instantiated
   from and MFD cell (platform device).
 
 - Incremental feature improvement in the Zynq, MCP23S08,
   DWAPB, OMAP, Xilinx and Crystalcove drivers.
 
 - Various minor fixes.

Pull networking updates from David Miller:
 "Most notable changes in here:

   1) By far the biggest accomplishment, thanks to a large range of
      contributors, is the addition of multi-send for transmit.  This is
      the result of discussions back in Chicago, and the hard work of
      several individuals.

      Now, when the ->ndo_start_xmit() method of a driver sees
      skb->xmit_more as true, it can choose to defer the doorbell
      telling the driver to start processing the new TX queue entires.

      skb->xmit_more means that the generic networking is guaranteed to
      call the driver immediately with another SKB to send.

      There is logic added to the qdisc layer to dequeue multiple
      packets at a time, and the handling mis-predicted offloads in
      software is now done with no locks held.

      Finally, pktgen is extended to have a "burst" parameter that can
      be used to test a multi-send implementation.

      Several drivers have xmit_more support: i40e, igb, ixgbe, mlx4,
      virtio_net

      Adding support is almost trivial, so export more drivers to
      support this optimization soon.

      I want to thank, in no particular or implied order, Jesper
      Dangaard Brouer, Eric Dumazet, Alexander Duyck, Tom Herbert, Jamal
      Hadi Salim, John Fastabend, Florian Westphal, Daniel Borkmann,
      David Tat, Hannes Frederic Sowa, and Rusty Russell.

   2) PTP and timestamping support in bnx2x, from Michal Kalderon.

   3) Allow adjusting the rx_copybreak threshold for a driver via
      ethtool, and add rx_copybreak support to enic driver.  From
      Govindarajulu Varadarajan.

   4) Significant enhancements to the generic PHY layer and the bcm7xxx
      driver in particular (EEE support, auto power down, etc.) from
      Florian Fainelli.

   5) Allow raw buffers to be used for flow dissection, allowing drivers
      to determine the optimal "linear pull" size for devices that DMA
      into pools of pages.  The objective is to get exactly the
      necessary amount of headers into the linear SKB area pre-pulled,
      but no more.  The new interface drivers use is eth_get_headlen().
      From WANG Cong, with driver conversions (several had their own
      by-hand duplicated implementations) by Alexander Duyck and Eric
      Dumazet.

   6) Support checksumming more smoothly and efficiently for
      encapsulations, and add "foo over UDP" facility.  From Tom
      Herbert.

   7) Add Broadcom SF2 switch driver to DSA layer, from Florian
      Fainelli.

   8) eBPF now can load programs via a system call and has an extensive
      testsuite.  Alexei Starovoitov and Daniel Borkmann.

   9) Major overhaul of the packet scheduler to use RCU in several major
      areas such as the classifiers and rate estimators.  From John
      Fastabend.

  10) Add driver for Intel FM10000 Ethernet Switch, from Alexander
      Duyck.

  11) Rearrange TCP_SKB_CB() to reduce cache line misses, from Eric
      Dumazet.

  12) Add Datacenter TCP congestion control algorithm support, From
      Florian Westphal.

  13) Reorganize sk_buff so that __copy_skb_header() is significantly
      faster.  From Eric Dumazet"

d5935b07da ARM64: SoC changes for 3.18 
Starting with 3.18, we are merging SoC-specific changes for arm64 through
 the arm-soc tree, like we have been doing for arm32.
 
 This time, there is only one set of changes, adding support for the
 Cavium "Thunder" Soc family. Since the changes are relatively small,
 this includes Kconfig, defconfig and DT changes.
 
 If all goes well, we will never require adding actual C source code
 for platform support in arm64, given that the architecture is more
 clearly defined and we have moved out a lot of the platform specifics
 into device drivers for arm32 already.

 "Starting with 3.18, we are merging SoC-specific changes for arm64
  through the arm-soc tree, like we have been doing for arm32.

  This time, there is only one set of changes, adding support for the
  Cavium "Thunder" Soc family.  Since the changes are relatively small,
  this includes Kconfig, defconfig and DT changes.

  If all goes well, we will never require adding actual C source code
  for platform support in arm64, given that the architecture is more
  clearly defined and we have moved out a lot of the platform specifics
  into device drivers for arm32 already"

8b45bc892e ARM: SoC driver updates for 3.18 
These are changes for drivers that are intimately tied to some SoC
 and for some reason could not get merged through the respective
 subsystem maintainer tree.
 
 Most of the new code is for the Keystone Navigator driver, which is
 new base support that is going to be needed for their hardware
 accelerated network driver and other units.
 
 Most of the commits are for moving old code around from at91 and omap
 for things that are done in device drivers nowadays.
 
 - at91: move reset, poweroff, memory and clocksource code into drivers
   directories
 - socfpga: add edac driver (through arm-soc, as requested by Boris)
 - omap: move omap-intc code to drivers/irqchip
 - sunxi: added an RTC driver for sun6i
 - omap: mailbox driver related changes
 - keystone: support for the "Navigator" component
 - versatile: new reboot, led and soc drivers

212fe84a6f ARM: SoC cleanups for 3.18 
This time around, the cleanup branch contains mostly code removal. A number
 of board files for at91, imx and msm have become obsolete because of the
 DT conversion and are now ready to be removed. The OMAP platform has
 traditionally had its own DMA engine abstraction and as this is being
 phased out, a lot of the original code is now unused and can be removed
 as well.
 
 S3C24xx can be simplified now that the restart code is a proper device
 driver.
 
 Finally, a number of cleanups in shmobile are done to prepare for
 the addition of new code in other branches.

 "These are bug fixes for harmless problems that were not important
  enough to get fixed in 3.17.  The majority of these are OMAP specific,
  but there are also a couple for Marvell mvebu, cns3xxx, and others, as
  well as some updates for the MAINTAINERS file.

  In particular, Robert Jarzmik and Daniel Mack now volunteered to help
  out maintaining the PXA platform, Krzysztof Halasa took over the
  cns3xxx platform, Carlo Caione is the maintainer for the new Amlogic
  meson platform, and Matthias Brugger is now listed for the mediatek

e4e65676f2 Fixes and features for 3.18. 
Apart from the usual cleanups, here is the summary of new features:
 
 - s390 moves closer towards host large page support
 
 - PowerPC has improved support for debugging (both inside the guest and
   via gdbstub) and support for e6500 processors
 
 - ARM/ARM64 support read-only memory (which is necessary to put firmware
   in emulated NOR flash)
 
 - x86 has the usual emulator fixes and nested virtualization improvements
   (including improved Windows support on Intel and Jailhouse hypervisor
   support on AMD), adaptive PLE which helps overcommitting of huge guests.
   Also included are some patches that make KVM more friendly to memory
   hot-unplug, and fixes for rare caching bugs.
 
 Two patches have trivial mm/ parts that were acked by Rik and Andrew.
