From: Matt Helsley <matthltc@us.ibm.com>

Now that the cgroup freezer system also calls thaw_process() inlining
these functions uses more space.  Uninlining returns some space:

Before:
	text	data	bss	dec	hex	filename
	4260872	275532	290816	4827220 49a854	vmlinux
After:
	text	data	bss	dec	hex	filename
	4260852	275532	290816	4827200	49a840	vmlinux
