I'm very unhappy with this kind of crap.

Has it been tested AT ALL? Apparently not.

	arch/x86/kernel/cpu/mcheck/mce.c:98: error: multiple storage classes in declaration specifiers
	arch/x86/kernel/cpu/mcheck/mce.c:98: error: non-static declaration of ʽper_cpu__mces_seenʼ follows static declaration
	arch/x86/kernel/cpu/mcheck/mce.c:98: note: previous declaration of ʽper_cpu__mces_seenʼ was here
	.. and tons of other similar errors ..

and it was apparently done on purpose, for no good reason. The bug with 
static per-cpu variables is only for some broken architectures.

Even the _documentation_ uses "static DEFINE_PER_CPU(..)" for chissake!

To make matters worse, this whole series was clearly rebased (or applied 
from some other queue) just _minutes_ before sending it to me. No wonder 
it had zero testing:

 - commit:

 - email:
	Date: Thu, 18 Jun 2009 17:07:16 +0900

I'm not pulling it. Or rather, I pulled it, ended up doing other work, 
noticed the problems, and had to re-do my whole tree because I refuse to 
have sh*t like this in the kernel.

And I'm not going to pull trees that get rebased like this with basically 
no testing before sending it to me. There's a reason I don't like 
rebasing.
