[SRU][Bionic][PATCH 0/1] KVM: PPC: Book3S HV: Fix guest r11 corruption with POWER9 TM workarounds

[Joseph Salisbury]

BugLink: https://bugs.launchpad.net/bugs/1792501

== SRU Justification ==
IBM is requesting this commit in Bionic.  It fixes a regression
introduced by upstream commit 4bb3c7a020.  

Without this patch, package installation segfaults inside debian chroot 
env in P9 KVM guest with HTM enabled.

The fix has already landed in Cosmic master-next.

== Fix ==
f14040bca892 ("KVM: PPC: Book3S HV: Fix guest r11 corruption with POWER9 TM workarounds")

== Regression Potential ==
Low.  This commit fixes an existing regrssion and is specific to powerpc.  It has been cc'd to
upstream stable, so has had additional upstream review.

== Test Case ==
A test kernel was built with this patch and tested by the original bug reporter.
The bug reporter states the test kernel resolved the bug.
