This fix is needed to resolve the crash
https://lists.ozlabs.org/pipermail/linuxppc-dev/2018-May/172835.html |
== SRU Justification ==
IBM reports a kernel crash with Bionic while in degraded mode(Degraded
cores).
IBM created a patch to resolve this bug and has submitted it upstream:
https://lists.ozlabs.org/pipermail/linuxppc-dev/2018-May/172835.html
The patch has not laned in mainline as of yet, so it is being submitted
as a SAUCE patch.
== Fix ==
UBUNTU: SAUCE: powerpc/perf: Fix memory allocation for core-imc based on num_possible_cpus()
== Regression Potential ==
Low. Limited to powerpc.
== 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.
