Merge patch series "RISC-V: hwprobe: Introduce which-cpus"

Andrew Jones <ajones@ventanamicro.com> says:

This series introduces a flag for the hwprobe syscall which effectively
reverses its behavior from getting the values of keys for a set of cpus
to getting the cpus for a set of key-value pairs.
