Pulled, thanks.
Paolo
Paolo or Radim, Please do a pull from my kvm-ppc-fixes-4.19-3 tag to get one commit that fixes a host crash that I have seen when a page fault on a radix guest on POWER9 happens concurrently with a THP collapse operation. The bug is only in 4.19-rc and hence the fix does not need to be backported to any stable kernel tree. Thanks, Paul. The following changes since commit 71d29f43b6332badc5598c656616a62575e83342: KVM: PPC: Book3S HV: Don't use compound_order to determine host mapping size (2018-09-12 08:50:50 +1000) are available in the git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/paulus/powerpc tags/kvm-ppc-fixes-4.19-3 for you to fetch changes up to 6579804c431712d56956a63b1a01509441cc6800: KVM: PPC: Book3S HV: Avoid crash from THP collapse during radix page fault (2018-10-04 14:51:11 +1000) ---------------------------------------------------------------- Third set of PPC KVM fixes for 4.19 One patch here, fixing a potential host crash introduced (or at least exacerbated) by a previous fix for corruption relating to radix guest page faults and THP operations. ---------------------------------------------------------------- Paul Mackerras (1): KVM: PPC: Book3S HV: Avoid crash from THP collapse during radix page fault arch/powerpc/kvm/book3s_64_mmu_radix.c | 10 ++++++++++ 1 file changed, 10 insertions(+)
