Paolo,

Please do a pull from my kvm-ppc-fixes-4.15-3 tag to get four commits
which I would like to have merged upstream for 4.15 if possible.
Three of them fix bugs in the hashed page table resizing code,
including a user-triggerable use-after-free bug.  The other one fixes
a bug that prevents PR KVM guests from running at all when PR KVM is
used to provide nested virtualization under PowerVM.

There is a kvm-ppc-fixes-4.15-2 tag in there that I did a month ago,
but I never got around to sending you a pull request before I went on
vacation.  This pull request includes those commits.

Thanks,
Paul.

  KVM: PPC: Book3S HV: Always flush TLB in kvmppc_alloc_reset_hpt() (2018-01-10 20:45:41 +1100)

----------------------------------------------------------------
PPC KVM fixes for 4.15

Four commits here, including two that were tagged but never merged.
Three of them are for the HPT resizing code; two of those fix a
user-triggerable use-after-free in the host, and one that fixes
stale TLB entries in the guest.  The remaining commit fixes a bug
causing PR KVM guests under PowerVM to fail to start.
