The problem with names based on that, like cpu_isolation_map, is that there's
really two concepts here: there's the isolcpus feature where the 'mask' is in fact
the CPUs that are isolated - while the 'housekeeping CPUs' is the mask of CPUs
that _support_ the isolated set of CPUs. The two are different roles but easily
confused if named similarly.

So I guess 'housekeeping CPUs' is as good as it gets for now.

Mind sending a refreshed queue against the latest kernel? There's some new
conflicts in kernel/watchdog.c for example.

Thanks,
