[GIT PULL] Please pull my kvm-ppc-next-4.18-2 tag

[Paul Mackerras <paulus@ozlabs.org>]

Hi Paolo,

It seems my previous pull request of 4 June might have got missed, or
buried in your inbox.  In any case, I have added some more fixes to my
kvm-ppc-next branch, and if you could pull the kvm-ppc-next-4.18-2 tag
and push that to Linus for 4.18, that would be very much appreciated.

I have checked that this branch merges cleanly with Linus' current
tree and boots and runs KVM successfully on POWER8 and POWER9.

This update is quite large; it includes a series to reimplement how we
do MMIO instruction emulation to use more of the common powerpc kernel
infrastructure, a series to improve radix page table handling on
POWER9, a series to add transactional memory support to PR KVM, plus
quite a few bug fixes.

Thanks,
Paul.

  KVM: PPC: Book3S PR: Fix failure status setting in tabort. emulation (2018-06-13 09:46:13 +1000)

----------------------------------------------------------------
PPC KVM update for 4.18

* Reimplement MMIO instruction emulation using analyse_instr, which avoids
  duplication of the instruction decoder and reduces code size.
* PR KVM improvements: implement support for transactional memory,
  and enable PR KVM on POWER9 guests running in HPT mode, plus
  quite a few bug-fixes.
* Radix page table improvements for POWER9.
* Improvements and bugfixes for IOMMU (TCE) support.
* Other miscellaneous fixes.
