§$%§$&&§! (please excuse my french).

And I build-tested this patch with randconfigs a whole night and didn't
see any issues. But I think I see what happens, the above is the result
of a chain of unfortunate events :-)

* Randy mistakenly reported the original randconfig issue against
3.1-rc1. However, in reality it was against linux-next. It was caused by
the fact that i7core_edac now needs to depend on X86_MCE_INTEL (which
pulls in X86_MCE for the notifier chain).

* I sent the proper fix which was for Mauro to apply _ontop_ of

git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/edac.git linux_next

where the rest of the i7core_edac changes are. This patch depends on them.

* I wasn't clear enough with the patch though, and I see Linus has
applied it already on his tree, which is clearly too early - it has to
go in in the next merge window together with the rest of the stuff in
Mauro's branch.

So, I guess we're reverting for now, Linus?

Thanks and sorry for the trouble.
