Paolo or Radim,
Please do a pull from my kvm-ppc-next-5.2-1 tag to get a PPC update
for 5.2. The main new feature here is that we can now let guests
access the POWER9 XIVE interrupt controller directly for things like
acknowledge, EOI, enable and disable on interrupts, rather than
requiring guests to do hypercalls for these operations.
I have merged in the topic/ppc-kvm branch from the powerpc tree
because one of the patches there is a prerequisite for the XIVE patch
series. That's why there are changes to arch/powerpc/kernel in the
diffstat.
Stephen Rothwell noted a conflict between my tree and the kvm-arm tree
because we have both allocated new capability numbers.
The XIVE patch series also modifies generic KVM code to add mmap and
release methods on KVM devices.
Thanks,
Paul.

----------------------------------------------------------------
PPC KVM update for 5.2
* Support for guests to access the new POWER9 XIVE interrupt controller
hardware directly, reducing interrupt latency and overhead for guests.
* In-kernel implementation of the H_PAGE_INIT hypercall.
* Reduce memory usage of sparsely-populated IOMMU tables.
* Several bug fixes.
