[kvm-unit-tests,0/3] riscv: Improve on-cpu and IPI support

Message

The first two patches improve general library support for cpumasks and
the on-cpus API. on-cpus can now take cpumasks for input. The last patch
improves support for sending IPIs on riscv using the SBI IPI extension
by supporting a nicer interface of cpuids and cpumasks.

Andrew Jones (3):
  lib/cpumask: Fix and simplify a few functions
  lib/on-cpus: Introduce on_cpumask and on_cpumask_async
  riscv: Introduce SBI IPI convenience functions
