Subject: Please pull hwpoison updates for 2.6.36
Date: Thu, 5 Aug 2010 20:37:34 +0200 [thread overview]
Message-ID: <20100805183734.GA9523@basil.fritz.box> (raw)
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.
