      Merge tag 'kvm-arm-for-3.15-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/kvmarm/kvmarm into kvm-master
      
      First round of KVM/ARM Fixes for 3.15
      
      Includes vgic fixes, a possible kernel corruption bug due to
      misalignment of pages and disabling of KVM in KConfig on big-endian
      systems, because the last one breaks the build.

      ARC: !PREEMPT: Ensure Return to kernel mode is IRQ safe · 8aa9e85a
      Vineet Gupta authored
      There was a very small race window where resume to kernel mode from a
      Exception Path (or pure kernel mode which is true for most of ARC
      exceptions anyways), was not disabling interrupts in restore_regs,
      clobbering the exception regs
      
      Anton found the culprit call flow (after many sleepless nights)
      
      | 1. we got a Trap from user land
      | 2. started to service it.
      | 3. While doing some stuff on user-land memory (I think it is padzero()),
      |     we got a DataTlbMiss
      | 4. On return from it we are taking "resume_kernel_mode" path
      | 5. NEED_RESHED is not set, so we go to "return from exception" path in
      |     restore regs.
      | 6. there seems to be IRQ happening

      perf x86: Fix perf to use non-executable stack, again · 6392b4eb
      Mathias Krause authored
      arch/x86/tests/regs_load.S is missing the linker note about the stack
      requirements, therefore making the linker fall back to an executable
      stack. As this object gets linked against the final perf binary, it'll
      needlessly end up with an executable stack. Fix this by adding the
      appropriate linker note.
      
      Also add a global linker flag to prevent future regressions, as
      suggested by Jiri. This way perf won't get an executable stack even if
      we fail to add the .GNU-stack linker note to future assembler files.
      Though, doing so might create regressions the other way around, when
      (statically) linking against libraries needing an executable stack.
      But, apparently, regressing in that direction is wanted as it is an
      indicator of poor code quality -- or just missing linker notes.

      perf machine: Search for modules in %s/lib/modules/%s · 61d4290c
      Richard Yao authored
      Modules installed outside of the kernel's build system should go into
      "%s/lib/modules/%s/extra", but at present, perf will only look at them
      when they are in "%s/lib/modules/%s/kernel". Lets encourage good
      citizenship by relaxing this requirement to "%s/lib/modules/%s". This
      way open source modules that are out-of-tree have no incentive to start
      populating a directory reserved for in-kernel modules and I can stop
      hex-editing my system's perf binary when profiling OSS out-of-tree
      modules.
      
      Feedback from Namhyung Kim correctly revealed that the hex-edits that I
      had been doing meant that perf was also traversing the build and source
      symlinks in %s/lib/modules/%s. That is undesireable, so we explicitly
      exclude them from traversal with a minor tweak to the traversal routine.
