Subject: [GIT PULL] arch/tile update for 3.5
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
