Merge branch 'for-3.5' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/percpu
Pull percpu updates from Tejun Heo:
"Contains Alex Shi's three patches to remove percpu_xxx() which overlap
with this_cpu_xxx(). There shouldn't be any functional change."
* 'for-3.5' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/percpu:
percpu: remove percpu_xxx() functions
x86: replace percpu_xxx funcs with this_cpu_xxx
net: replace percpu_xxx funcs with this_cpu_xxx or __this_cpu_xxx
