FYI, this commit triggered a -tip test failure:

 arch/x86/kernel/cpu/mcheck/mce-xeon75xx.c: In function 'xeon75xx_mce_init':
 arch/x86/kernel/cpu/mcheck/mce-xeon75xx.c:340: error: implicit declaration of function 'pci_match_id'

I'm excluding it from tip:master.

But the bigger problem with this commit is structure of it - or the lack 
thereof.

It just blindly goes into the direction the MCE code has been going for some 
time, minimally enabling the hardware, ignoring both the new EDAC design and 
the new performance monitoring related design i outlined some time ago.

Newly introduced MCE code in the x86 tree should be integrated much better 
into existing higher level facilities, not just limp along ignoring life 
outside of its little box. This will have to be addressed before we can 
reintroduce this commit, even if this trivial build failure is addressed.

I've Cc:-ed a few more interested parties.

Thanks,

	Ingo
