[GIT PULL] (xen) stable/for-jens-3.9

[Konrad Rzeszutek Wilk]

Hey Jens,

Please git pull the following branch:

 git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen.git stable/for-jens-3.9

which has a bunch of fixes. They vary from being able to deal with unknown
requests, overflow in statistics, compile warnings, bug in the error path,
removal of unnecessary logic. There is also one performance fix - which is
to allocate pages for requests when the driver loads - instead of doing it
per request.

That is it. Please pull!
