Merge patch series "riscv: Create and document PR_RISCV_SET_ICACHE_FLUSH_CTX prctl"
Charlie Jenkins <charlie@rivosinc.com> says:
Improve the performance of icache flushing by creating a new prctl flag
PR_RISCV_SET_ICACHE_FLUSH_CTX. The interface is left generic to allow
for future expansions such as with the proposed J extension [1].
Documentation is also provided to explain the use case.
Patch sent to add PR_RISCV_SET_ICACHE_FLUSH_CTX to man-pages [2].
