      Pull btrfs fixes from Chris Mason:
       "This has our collection of bug fixes.  I missed the last rc because I
        thought our patches were making NFS crash during my xfs test runs.
        Turns out it was an NFS client bug fixed by someone else while I tried
        to bisect it.
      
        All of these fixes are small, but some are fairly high impact.  The
        biggest are fixes for our mount -o remount handling, a deadlock due to
        GFP_KERNEL allocations in readdir, and a RAID10 error handling bug.
      
        This was tested against both 3.3 and Linus' master as of this morning."

      Revert "autofs: work around unhappy compat problem on x86-64" · fcbf94b9
      Linus Torvalds authored
      This reverts commit a32744d4
      
      .
      
      While that commit was technically the right thing to do, and made the
      x86-64 compat mode work identically to native 32-bit mode (and thus
      fixing the problem with a 32-bit systemd install on a 64-bit kernel), it
      turns out that the automount binaries had workarounds for this compat
      problem.
      
      Now, the workarounds are disgusting: doing an "uname()" to find out the
      architecture of the kernel, and then comparing it for the 64-bit cases
      and fixing up the size of the read() in automount for those.  And they
      were confused: it's not actually a generic 64-bit issue at all, it's
      very much tied to just x86-64, which has different alignment for an
      'u64' in 64-bit mode than in 32-bit mode.
      
      But the end result is that fixing the compat layer actually breaks the
      case of a 32-bit automount on a x86-64 kernel.
      
      There are various approaches to fix this (including just doing a
      "strcmp()" on current->comm and comparing it to "automount"), but I
      think that I will do the one that teaches pipes about a special "packet
      mode", which will allow user space to not have to care too deeply about
      the padding at the end of the autofs packet.
      
      That change will make the compat workaround unnecessary, so let's revert
      it first, and get automount working again in compat mode.  The
      packetized pipes will then fix autofs for systemd.

      drm/i915: Set the Stencil Cache eviction policy to non-LRA mode. · 3a69ddd6
      Kenneth Graunke authored
      Clearing bit 5 of CACHE_MODE_0 is necessary to prevent GPU hangs in
      OpenGL programs such as Google MapsGL, Google Earth, and gzdoom when
      using separate stencil buffers.  Without it, the GPU tries to use the
      LRA eviction policy, which isn't supported.  This was supposed to be off
      by default, but seems to be on for many machines.
      
      This cannot be done in gen6_init_clock_gating with most of the other
      workaround bits; the render ring needs to exist.  Otherwise, the
      register write gets dropped on the floor (one printk will show it
      changed, but a second printk immediately following shows the value
      reverts to the old one).

      Pull Xen fixes from Konrad Rzeszutek Wilk:
       "Some of these had been in existence since the 2.6.27 days, some since
        3.0 - and some due to new features added in v3.4.
      
        The one that is most interesting is David's one - in the low-level
        assembler code we had be checking events needlessly.  With his patch
        now we do it when the appropriate flag is set - with the added benefit
        that we can process events faster.  Stefano's is fixing a mistake
        where the Linux IRQ numbers were ACK-ed instead of the Xen IRQ,
        resulting in missing interrupts.  The other ones are bootup related
        that can show up on various hardware."
      
       - In the low-level assembler code we would jump to check events even if
         none were present.  This incorrect behavior had been there since
         2.6.27 days!
       - When using the fast-path for ACK-ing interrupts we were using the
         Linux IRQ numbers instead of the Xen ones (and they can differ) and
         missing interrupts in process.
       - Fix bootup crashes when ACPI hotplug CPUs were present and they would
         expand past the set number of CPUs we were allocated.
       - Deal with broken BIOSes when uploading C-states to the hypervisor.
       - Disable the cpuid check for MWAIT_LEAF if the ACPI PAD driver is
         loaded.  If the ACPI PAD driver is used it will crash, so lets not
         export the functionality so the ACPI PAD driver won't load.

      Pull build fixes for less mainstream architectures from Paul Gortmaker:
       "These are fixes for frv(1), blackfin(2), powerpc(1) and xtensa(4).
      
        Fortunately the touches are nearly all specific to files just used by
        the arch in question.  The two touches to shared/common files
        [kernel/irq/debug.h and drivers/pci/Makefile] are trivial to assess as
        no risk to anyone.
      
        Half of them relate to xtensa directly.  It was only when I fixed the
        last xtensa issue that I realized that the arch has been broken for a
        significant time, and isn't a specific v3.4 regression.  So if you
        wanted, we could leave xtensa lying bleeding in the street for a
        couple more weeks and queue those for 3.5.  But given they are no risk
        to anyone outside of xtensa, I figured to just leave them in.
      
        If you are OK with taking the xtensa fixes, then please pull to get:
      
         - one last implicit include uncovered by system.h that is in a file
           specific to just one powerpc defconfig.  (I'd sync'd with BenH).
      
         - fix an oversight in the PCI makefile where shared code wasn't being
           compiled for ARCH=frv
      
         - fix a missing include for GPIO in blackfin framebuffer.
      
         - audit and tag endif in blackfin ezkit board file, in order to find
           and fix the misplaced endif masking a block of code.
      
         - fix irq/debug.h choice of temporary macro names to be more internal
           so they don't conflict with names used by xtensa.
      
         - fix a reference to an undeclared local var in xtensa's signal.c
      
         - fix an implicit bug.h usage in xtensa's asm/io.h uncovered by my
           removing bug.h from kernel.h
      
         - fix xtensa to properly indicate it is using asm-generic/hardirq.h
           in order to resolve the link error - undefined ack_bad_irq
      
        The xtensa still fails final link as my latest binutils does something
        evil when ld forward-relocates unlikely() blocks, but in theory people
        who have older/valid toolchains could now use the thing."
