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.
* b4-shazam-merge:
RISC-V: selftests: Add which-cpus hwprobe test
RISC-V: hwprobe: Introduce which-cpus flag
RISC-V: Move the hwprobe syscall to its own file
RISC-V: hwprobe: Clarify cpus size parameter
