SRU Justification/Impact: The upstream process for stable tree updates is quite similar in scope to the Ubuntu SRU process, e.g., each patch has to demonstrably fix a bug, and each patch is vetted by upstream by originating either directly from Linus' tree or in a minimally backported form of that patch. The 2.6.31.10 and 2.6.31.11 upstream stable patch set is now available. It should be included in the Ubuntu kernel as well. We do these updates together since 2.6.31.11 has only a single patch which reverts a patch from 2.6.31.10. We do the updates together so as to be in sync with upstream stable updates and not break any builds.
TEST CASE: TBD

== Fixes Bugs ==
* Bug 435958 - fixed with "acerhdf: limit modalias matching to supported"
* Bug 490068 - fixed with "USB: option: support hi speed for modem Haier CE100"
* Bug 253874 - fixed with "Input: atkbd - add force relese key quirk for Samsung R59P/R60P/R61P"
==Reverted existing commits==
* commit 230e81c3440cdfc5f931755cece4f1181a3b1374 (UBUNTU: [Upstream] acerhdf: Limit modalias matching to supported boards) was reverted in favor of an upstream patch in 2.6.31.10.
The patch sets are committed to the git repositories and not yet released. Hence changing the fix released to fix committed instead.
