[GIT PULL] arch/tile update for 3.5

[Chris Metcalf]

Linus,

Please pull the following changes for 3.5 from:

  git://git.kernel.org/pub/scm/linux/kernel/git/cmetcalf/linux-tile.git master

These changes cover a range of new arch/tile features and optimizations.
They've been through LKML review and on linux-next for a month or so.
There's also one bug-fix that just missed 3.4, which I've marked for stable.

Chris Metcalf (15):
      arch/tile: use interrupt critical sections less
      arch/tile: allow building Linux with transparent huge pages enabled
      arch/tile: support building big-endian kernel
      arch/tile: optimize get_user/put_user and friends
      arch/tile: Allow tilegx to build with either 16K or 64K page size
      arch/tile: support <asm/cachectl.h> header for cacheflush() syscall
      arch/tile: support kexec() for tilegx
      mm: add new arch_make_huge_pte() method for tile support
      arch/tile: support multiple huge page sizes dynamically
      arch/tile: fix hardwall for tilegx and generalize for idn and ipi
      arch/tile: allow querying cpu module information from the hypervisor
      arch/tile: add descriptive text if the kernel reports a bad trap
      arch/tile: mark TILEGX as not EXPERIMENTAL
      tile: fix bug where fls(0) was not returning 0
      tile: default to tilegx_defconfig for ARCH=tile

Kautuk Consul (1):
      tile/mm/fault.c: Port OOM changes to handle_page_fault
