it needs at least to include asm/mce.h for all the missing types, but the bigger problem
is that CONFIG_EDAC_MCE not being select'd means that we never build edac_mce.o
(it's an unselectable bool in drivers/edac/Kconfig)

I mistakenly reported this as a linux 3.1-rc1 build error when in fact it
was a linux-next build error, as Borislav pointed out.

Borislav, did you mean for this patch to be applied to mainline or are there also
patches in linux-next that are needed for mainline with this one?
