[GIT PULL] Please pull my kvm-ppc-fixes-4.19-2 tag

[Paul Mackerras <paulus@ozlabs.org>]

Paolo or Radim,

Please do a pull from my kvm-ppc-fixes-4.19-2 tag to get two commits
that should go into 4.19 because they fix host crashes and memory
corruption that can occur on POWER machines when the memory backing a
guest contains transparent huge pages.

Thanks,
Paul.

The following changes since commit bdf7ffc89922a52a4f08a12f7421ea24bb7626a0:

  KVM: PPC: Book3S HV: Don't use compound_order to determine host mapping size (2018-09-12 08:50:50 +1000)

----------------------------------------------------------------
Second set of PPC KVM fixes for 4.19

Two fixes for KVM on POWER machines.  Both of these relate to memory
corruption and host crashes seen when transparent huge pages are
enabled.  The first fixes a host crash that can occur when a DMA
mapping is removed by the guest and the page mapped was part of a
transparent huge page; the second fixes corruption that could occur
when a hypervisor page fault for a radix guest is being serviced at
the same time that the backing page is being collapsed or split.
