I have applied this to linux-next today.  It is not clear to me if this
is a fix for the cpu_alloc tree or the zero-based per_cpu area patches or
a combination of both.  If the first, please apply this to the cpu_alloc
tree or I will have to drop the tree.  Otherwise, let me know where it
belongs.

Also, considering the "discussions" between Rusty and yourself, I may
need to drop the cpu_alloc tree until they are resolved.
