qemu/0010-PPC-KVM-Disable-mmu-notifier-check.patch
Andreas Färber 36ac86c950 Accepting request 487699 from home:bfrogers:branches:Virtualization
Update to rc4 of v2.9.0. Also includes a few other fixes, and a number of tweaks to the spec files. I'd be happy to answer any questions about all those spec file changes, I believe they were all in the direction of a more correct and maintainable spec file. Since this is still in rc phase, let's keep it in devel project. Final release should appear in time for Beta2 of SLE12SP3. Delta from previous: Added Alex's patch for keyboard empty event.

Subject: [PATCH] PPC: KVM: Disable mmu notifier check
When using hugetlbfs (which is required for HV mode KVM on 970), we
check for MMU notifiers that on 970 can not be implemented properly.
So disable the check for mmu notifiers on PowerPC guests, making
KVM guests work there, even if possibly racy in some odd circumstances.
