How do you want to handle fixes for the mpam driver? Currently its hidden
behind CONFIG_EXPERT as there is no user-interface to it yet, but these are
the issues that can be hit with mainline today.

The first fixes a dereference of an uninitialised variable when restoring state
following cpuhp. The other two are warnings in the kunit code. (which I wouldn't
send now without the first one).

Applied to arm64 (for-next/fixes), thanks!
