Merge branch 'stable' of git://git.kernel.org/pub/scm/linux/kernel/git/cmetcalf/linux-tile
Pull tilepro fix from Chris Metcalf:
"This change allows the older tilepro architecture to be correctly
built by newer gccs, despite a change that caused gcc to start trying
to use an out-of-line implementation for __builtin_ffsll().
This should be inline again starting with gcc 4.7.4 and 4.8.2 or so,
but meanwhile this change keeps things from breaking, with the only
cost being a few bytes of code in the kernel to provide __ffsdi2 even
for compilers that do inline it"
* 'stable' of git://git.kernel.org/pub/scm/linux/kernel/git/cmetcalf/linux-tile:
tilepro: work around module link error with gcc 4.7
