Paolo or Radim,

Please do a pull from my kvm-ppc-fixes-5.2-1 tag to get a series of
commits which should go into 5.2 (i.e. via the master branch of the
kvm tree).  They are mostly fixes for the new code which allows guests
to access the XIVE interrupt controller on POWER9 machines directly,
and locking fixes to solve host deadlock issues.

It turns out that the PPC KVM code had been using the kvm->lock mutex
in several places where the vcpu mutex was already held.  Although
this is contrary to what Documentation/virtual/kvm/locking.txt says,
lockdep didn't complain about it in the past because we (apparently)
had no places where a vcpu mutex was taken with kvm->lock held.  Now
there is such a place, in the recently-added XIVE code.  Thus we now
need to fix those other places that take the locks in the wrong order.

Thanks,
Paul.

Paolo or Radim,

Please do a pull from my kvm-ppc-fixes-5.3-1 tag to get one small
commit which I would like to go to Linus for 5.3 if possible, since it
fixes a bug where a malicious guest could cause host CPUs to hang
hard.  The fix is small and obviously correct.

Thanks,
Paul.

Paolo or Radim,

Please do a pull from my kvm-ppc-fixes-5.4-1 tag to get a commit which
fixes a potential host crash.  I have based my tree on 5.4-rc3 because
there is another KVM fix which is included in 5.4-rc3, having gone
upstream via Michael Ellerman's tree.

Thanks,
Paul.

Paolo,

Please do a pull from my kvm-ppc-fixes-5.7-1 tag to get one commit
which fixes a regression introduced in the 5.7 merge window by one of
my patches.  It causes guests in HPT mode occasionally to get a
spurious EFAULT error return from KVM_RUN, which tends to cause them
to die.

Paul.
