Paolo or Radim,
Please do a pull from my kvm-ppc-next-4.17-1 tag to get a PPC KVM
update for the 4.17 merge window. What's in here is a series that
improves the radix page fault handler for POWER9 systems and makes it
use the generic __gfn_to_pfn_memslot() function. At this stage I am
just using that function as-is without the changes we discussed some
time ago; that can be optimized in future.
There are two other series that affect PPC KVM and also other powerpc
code. Michael Ellerman has put them in the topic/ppc-kvm branch in his
powerpc tree and merged them into his next branch. I have not merged
that topic branch into my kvm-ppc-next branch because there were no
conflicts to resolve and so those changes might as well just go in
through Michael's tree. There was a series that adds hypervisor
assistance for transactional memory, allowing KVM guests to use TM on
POWER9 systems, and a series that disables use of data watchpoints on
POWER9 because of hardware bugs.
Thanks,
Paul.
