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
