Merge branch 'for-3.8' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/percpu
Pull percpu changes from Tejun Heo:
"Nothing exciting here either. Joonsoo's is almost cosmetic. Cyrill's
patch fixes "percpu_alloc" early kernel param handling so that the
kernel doesn't crash when the parameter is specified w/o any argument."
* 'for-3.8' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/percpu:
mm, percpu: Make sure percpu_alloc early parameter has an argument
percpu: make pcpu_free_chunk() use pcpu_mem_free() instead of kfree()
