       "A surprisingly small batch of fixes for -rc3.  Suspiciously small, I'd
        say.
      
        Anyway, most of this are a few defconfig updates.  Some for omap to
        deal with kernel binary size (moving ipv6 to module, etc).  A larger
        one for socfpga that refreshes with some churn, but also turns on a
        few options that makes the newly-added board in my bootfarm usable for
        testing.
      
        OMAP3 will also now warn when booted with legacy (non-DT) boot
        protocols, hopefully encouraging those who still care about some of
        those platforms to submit DT support and report bugs where needed.
        Nothing stops working though, this is just to warn for future
        deprecation.
      
        Beyond this, very few actual bugfixes.  A PXA fix for DEBUG_LL boot
        hangs, a missing terminting entry in a dt_match array on RealView a

      ftracetest: Take the first debugfs mount found · e7dbb489
      Steven Rostedt (Red Hat) authored
      Running ftracetests on a box that mounted debugfs in two locations
      made the ftracetests fail. This is because the tests uses a grep
      of debugfs from the /proc/mounts file to find the debugfs mount
      point, and then appends "/tracing" to that string to get the tracing
      directory.
      
      If the debugfs directory is mounted twice, then that grep will return
      two answers and appending "/tracing" to a string with two lines will
      not work.
      
      Use "head -1" to only take the first mount point found.

      powerpc: Convert power off logic to pm_power_off · 9178ba29
      Alexander Graf authored
      The generic Linux framework to power off the machine is a function pointer
      called pm_power_off. The trick about this pointer is that device drivers can
      potentially implement it rather than board files.
      
      Today on powerpc we set pm_power_off to invoke our generic full machine power
      off logic which then calls ppc_md.power_off to invoke machine specific power
      off.
      
      However, when we want to add a power off GPIO via the "gpio-poweroff" driver,
      this card house falls apart. That driver only registers itself if pm_power_off
      is NULL to ensure it doesn't override board specific logic. However, since we
      always set pm_power_off to the generic power off logic (which will just not
      power off the machine if no ppc_md.power_off call is implemented), we can't
      implement power off via the generic GPIO power off driver.
      
      To fix this up, let's get rid of the ppc_md.power_off logic and just always use
      pm_power_off as was intended. Then individual drivers such as the GPIO power off
      driver can implement power off logic via that function pointer.
      
      With this patch set applied and a few patches on top of QEMU that implement a
      power off GPIO on the virt e500 machine, I can successfully turn off my virtual
      machine after halt.

      powerpc: Replace __get_cpu_var uses · 69111bac
      Christoph Lameter authored
      This still has not been merged and now powerpc is the only arch that does
      not have this change. Sorry about missing linuxppc-dev before.
      
      V2->V2
        - Fix up to work against 3.18-rc1
      
      __get_cpu_var() is used for multiple purposes in the kernel source. One of
      them is address calculation via the form &__get_cpu_var(x).  This calculates
      the address for the instance of the percpu variable of the current processor
      based on an offset.
      
      Other use cases are for storing and retrieving data from the current
      processors percpu area.  __get_cpu_var() can be used as an lvalue when
      writing data or on the right side of an assignment.
      
      __get_cpu_var() is defined as :
      
      __get_cpu_var() always only does an address determination. However, store
      and retrieve operations could use a segment prefix (or global register on
      other platforms) to avoid the address calculation.
      
      this_cpu_write() and this_cpu_read() can directly take an offset into a
      percpu area and use optimized assembly code to read and write per cpu
      variables.
      
      This patch converts __get_cpu_var into either an explicit address
      calculation using this_cpu_ptr() or into a use of this_cpu operations that
      use the offset.  Thereby address calculations are avoided and less registers
      are used when code is generated.
      
      At the end of the patch set all uses of __get_cpu_var have been removed so
      the macro is removed too.
      
      The patch set includes passes over all arches as well. Once these operations
      are used throughout then specialized macros can be defined in non -x86
      arches as well in order to optimize per cpu access by f.e.  using a global
      register that may be set to the per cpu base.
      
      Transformations done to __get_cpu_var()
      
      1. Determine the address of the percpu instance of the current processor.
      
      	DEFINE_PER_CPU(int, y);
      	int *x = &__get_cpu_var(y);
      
          Converts to
      
      	int *x = this_cpu_ptr(&y);
      
      2. Same as #1 but this time an array structure is involved.
      
      	DEFINE_PER_CPU(int, y[20]);
      	int *x = __get_cpu_var(y);
      
          Converts to
      
      	int *x = this_cpu_ptr(y);
      
      3. Retrieve the content of the current processors instance of a per cpu
      variable.
      
      	DEFINE_PER_CPU(int, y);
      	int x = __get_cpu_var(y)
      
         Converts to
      
      	int x = __this_cpu_read(y);
      
      4. Retrieve the content of a percpu struct
      
      	DEFINE_PER_CPU(struct mystruct, y);
      	struct mystruct x = __get_cpu_var(y);
      
         Converts to
      
      	memcpy(&x, this_cpu_ptr(&y), sizeof(x));
      
      5. Assignment to a per cpu variable
      
      	DEFINE_PER_CPU(int, y)
      	__get_cpu_var(y) = x;
      
         Converts to
      
      	__this_cpu_write(y, x);
      
      6. Increment/Decrement etc of a per cpu variable
      
      	DEFINE_PER_CPU(int, y);
      	__get_cpu_var(y)++
      
         Converts to
      
      	__this_cpu_inc(y)

       "Three main MTD fixes for 3.18:
      
         - A regression from 3.16 which was noticed in 3.17.  With the
           restructuring of the m25p80.c driver and the SPI NOR library
           framework, we omitted proper listing of the SPI device IDs.  This
           means m25p80.c wouldn't auto-load (modprobe) properly when built as
           a module.  For now, we duplicate the device IDs into both modules.
      
         - The OMAP / ELM modules were depending on an implicit link ordering.
           Use deferred probing so that the new link order (in 3.18-rc) can
           still allow for successful probing.

      Merge "omap fixes against v3.18-rc2" from Tony Lindgren:
      
      Few fixes for omaps to enable NAND BCH so devices won't
      produce errors when booted with omap2plus_defconfig, and
      reduce bloat by making IPV6 a loadable module.
      
      Also let's add a warning about legacy boot being deprecated
      for omap3.
      
      We now have things working with device tree, and only omap3 is
      still booting in legacy mode. So hopefully this warning will
      help move the remaining legacy mode users to boot with device
      tree.
      
      As the total reduction of code and static data is somewhere
      around 20000 lines of code once we remove omap3 legacy mode
      booting, we really do want to make omap3 to boot also in
      device tree mode only over the next few merge cycles.

      irda: stop calling sk_prot->disconnect() on connection failure · 4cb8c359
      Linus Torvalds authored
      The sk_prot is irda's own set of protocol handlers, so irda should
      statically know what that function is anyway, without using an indirect
      pointer.  And as it happens, we know *exactly* what that pointer is
      statically: it's NULL, because irda doesn't define a disconnect
      operation.
      
      So calling that function is doubly wrong, and will just cause an oops.

      drm/exynos: correct connector->dpms field before resuming · 74cfe07a
      Andrzej Hajda authored
      During system suspend after connector switch off its dpms field
      is set to connector previous dpms state. To properly resume dpms field
      should be set to its actual state (off) before resuming to previous dpms state.

      Before DPMS off driver disables vblank.
      It should be balanced by vblank enable after DPMS on.
      The patch fixes issue with page_flip ioctl not being able
      to acquire vblank counter introduced by patch:
      drm: Always reject drm_vblank_get() after drm_vblank_off()

      drm/exynos: init kms poll at the end of initialization · 3cb6830a
      Andrzej Hajda authored
      HPD events can be generated by components even if drm_dev is not fully
      initialized, to skip such events kms poll initialization should
      be performed at the end of load callback followed directly by forced
      connection detection.

      All KMS objects are destroyed by drm_mode_config_cleanup in proper order
      so component drivers should not care about it.
