These changes are simple and straightforward. Let's them go first.

Paolo, I am sending these patches without taking into account your
patchset with header cleanup. Should we do something? I would be also
be happy to hear news about remaining patches from Andrey about HyperV
panic.
They didn't compile on ARM or Win32, hence the header file changes which
delayed them a bit.  But I still plan to send out the pull request very
soon, maybe today (ouch, it's already 12:30).

I wanted to include the record-replay patches, but they are big enough
that they probably deserve their own pull request, and my queue already
has 23 patches...

Please let us know is something from our side will improve the
situation.
No, it's just my issue.

However, there is something we can improve about the process.  QEMU
typically updates header files around 4.3-rc5 (by importing the changes
destined to 4.4), so we need a place to put this kind of patch that
depends on Linux header changes.  Therefore:

1) I've made a staging branch uq/hyperv (uq = upstream queue) on
git://git.kernel.org/pub/scm/virt/kvm/qemu-kvm.git - you can base your
patches on that branch as soon as I create it.

2) if you have more changes to asm/hyperv.h, bundle them and send them
to address@hidden  I'll include them in kvm/queue all at the same
time, which will make header file synchronization less of a problem in
the future.

Paolo

that sounds great to me. OK, will do.
