cgroup fixes for v6.2-rc7

During v6.2 cycle, there were a series of changes to task cpu affinity
handling which fixed cpuset inadvertently clobbering user-configured
affinity masks. Unfortunately, they broke the affinity handling on hybrid
heterogeneous CPUs which have cores that can execute both 64 and 32bit along
with cores that can only execute 32bit code.

This late pull request contains two fix patches for the above issue. While
reverting the changes that caused the regression is definitely an option,
the origial patches do improve how cpuset behave signficantly in some cases
and the fixes seem fairly safe, so I think it'd be better to try to fix them
first.
