Subject: Please pull hwpoison updates for 2.6.36


Linus,

Please pull the hwpoison updates for 2.6.36. This adds basic support for 
uncorrected memory MCA recovery for huge pages. I have some more stuff
(like better handling for slab errors) but it needs a bit more cooking, 
so currently only Horiguchi-san's code is included.

The rmap/hugetlb changes have been reviewed and blessed by the usual
suspects.  The rmap changes largely use existing infrastructure 
with just a few tweaks. There is no additional significant overhead for
the non error case.
