[PATCH 0/2] rust: cpumask: Bindings for core cpumasks and cpumask iterators

[Mitchell Levy]

The kernel provides a number of very useful CPU masks from the C side,
including CPU masks for possible and online CPUs. In particular, these
are very useful when some operation must be done on each CPU (either
each possible CPU or each online CPU, etc). Therefore, it seems to make
sense to add both of these functionalities at once.

These patches originated as part of my work on a Rust per-CPU API [1].
Boqun suggested to me that these may make sense to merge separately, and
it does seem like these might be useful beyond the per-CPU work.
