[GIT PULL] (xen) stable/for-jens-3.5 for 3.5-rc2..
Hey Jens, Please pull: git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen.git stable/for-jens-3.5 it has two critical fixes to deal with 32/64 guest/host combinations when sending DISCARD commands. They weren''t properly sent resulting in the guest crashing (https://bugzilla.redhat.com/show_bug.cgi?id=824641) The fix is in the backend (blkback) and the frontend has some extra WARN_ON added to diagnose similar issues like this in the future. Or if you prefer - I can stick those two patches in my tree and send them to Linus in my git pull this Friday with your Ack-ed by tag. Thanks!
