Not that I'm aware of -- you volunteering?

Looks like all 3 cpu_xxx_map references (online, present and possible)
that crash potentially uses need to be able to recognize and handle the
need to access them via their cpu_xxx_mask variables.  And as always,
to maintain backwards-compatibility, i.e., to recognize when neither
cpu_xxx_map and cpu_xxx_mask exist, such as in really older kernels...

Let us know if you can undertake the task.
