[SRU][Bionic][PATCH 0/2] Fixes for LP:1777194

[Joseph Salisbury]

== SRU Justification ==
IBM has seen hard lockups when running stress tests against Bionic.
These test sometimes lead to rcu_stalls.  IBM found that this bug is
resolved with commits 6bed3237624e and ac61c1156623.

== Fixes ==
6bed3237624e ("powerpc: use NMI IPI for smp_send_stop")
ac61c1156623 ("powerpc: Fix smp_send_stop NMI IPI handling")

== Regression Potential ==
Low.  Limited to powerpc.

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

Nicholas Piggin (2):
  powerpc: use NMI IPI for smp_send_stop
  powerpc: Fix smp_send_stop NMI IPI handling
