[GIT PULL] (xen) stable/for-jens-4.5

[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-4.5

which has one bug-fix. I had it in my tree at some point and after an rebase
(done months ago) lost it!

It solves an migration problem where the number of queues may differ from
one host to another.

Are they 4.5 material or not?

Hey Jens,

Please git pull the following branch:

  git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen.git stable/for-jens-4.5

which has three fixes for the Xen block drivers. They are quite simple
fixes. I was not entirely sure which branch to base them on - but they apply
just fine to for-4.5/drivers, for-linus, and for-4.6/drivers.

Thanks!

Pulled, sorry for the delay, I had some vacation post New Years that I 
still haven't caught fully up on.

[GIT PULL] (xen) stable/for-jens-4.5

[Konrad Rzeszutek Wilk]

Hey Jens,

Please pull in your "for-4.5/drivers" branch the following branch:

git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen.git stable/for-jens-4.5

which is based on "bcache: Change refill_dirty() to always scan entire disk if necessary"
(the tip of your branch as of today)

The pull is based on converting the backend driver into an multiqueue
driver and exposing more than one queue to the frontend. As such we had
to modify the frontend and also fix a bunch of bugs around this.

The original work is based on Arianna Avanzini's work as an OPW intern.
Bob took over the work and had been massaging it for quite some time.

Also included are are features to 64KB page support for ARM and various
bug-fixes.

Thank you!

P.S.
The branch is fresh in the git tree, but that is because I had rebased it
on your tree today (and tested it naturally). It had been simmering for
quite a while.
