Subject: [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!

Konrad Rzeszutek Wilk (2):
xen/blkback: Copy id field when doing BLKIF_DISCARD.
xen/blkfront: Add WARN to deal with misbehaving backends.
