Linus,

Please pull for 2.6.37 from

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

This fixes three tile-specific bug fixes that have been uncovered in
the last few weeks of testing.

Chris Metcalf (3):
arch/tile: fix rwlock so would-be write lockers don't block new readers
arch/tile: make glibc's sysconf(_SC_NPROCESSORS_CONF) work correctly
arch/tile: fix memchr() not to dereference memory for zero length
