      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).
