Thanks, Zhujh for figuring this out.  Those two patches weren't
taggled with cc: stable@...r.kernel.org, but they probably should have
been.  Since they first appeared in v3.0, the two long-term stable
kernels that would benefit with these patches are v3.0.x and v3.2.x.

Willy, Paul, would you consider cherry-picking the following commits
for your respective stable kernels?

git cherry-pick 7ad8e4e6ae2a7c95445ee1715b1714106fb95037
git cherry-pick 6976a6f2acde2b0443cd64f1d08af90630e4ce81

Thanks!!
