[GIT PULL] (xen) stable/for-linus-3.9-rc3-tag

Hey Linus,

Please git pull the following tag:

 git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen.git stable/for-linus-3.9-rc3-tag

which is full of fixes. The signed tag has the details (as always) but
this is mostly just the last stragglers of the regression bugs that this
merge window had. There are also two normal bug-fixes in the lot.

P.S.
We are working out the kinks in an early warning #linux-next testing framework
so that it can give us heads up in the future - so the when the next merge
window opens we shouldn't have surprises.

Please pull!

Unless I am looking in the wrong place, this patch is still the same one
that breaks PV on HVM and Xen ARM guests, see:

http://marc.info/?l=xen-devel&m=136377731913034

David is aware of the issue and I think is working on an alternative
fix.

Konrad?

I'll hold off on the pull request for now.

Thank you for noticing that. Linus does not look to have pulled it - so 
we still have some time
to fix this right.

Konrad,

I've just posted an updated version of this patch.  I'd suggest waiting
for an ack from Stefano before applying it.
