[PATCH v3 0/6] lib: Extend bitmap find binary operations

[Mathieu Desnoyers <mathieu.desnoyers@efficios.com>]

Extend bitmap find.h and cpumask.h with additional binary operations
such as "nor".

Also extend the testing and benchmark coverage of those bitmap find with
binary operations.

This is useful for NUMA-aware rseq concurrency IDs which depend on this
series. The series can be found at:
