Bug Description
== SRU Justification ==
IBM is requesting these two commits in Xenial, which are already
in Artful and Bionic. These commits allow identifying the microcode level
[MCL] of a [Z] system, hence let's one [IBM] know if the level includes
mitigation for Spectre or not.
Both commits are in mailine as of v4.12-rc1.
== Fixes ==
09214545c4a4 ("s390/bitops: add for_each_
157467ba9fb7 ("s390/cpuinfo: show facilities as reported by stfle")
== Regression Potential ==
Low. These fixes are specific to s390.
== Original Bug Description ==
Please backport this upstream commit:
