tools headers UAPI: Sync linux/prctl.h with the kernel sources
To pick the changes in:
628d701f2de5b9a1 ("powerpc/dexcr: Add DEXCR prctl interface")
6b9391b581fddd85 ("riscv: Include riscv_set_icache_flush_ctx prctl")
That adds some PowerPC and a RISC-V specific prctl options:
$ tools/perf/trace/beauty/prctl_option.sh > before
$ cp include/uapi/linux/prctl.h tools/perf/trace/beauty/include/uapi/linux/prctl.h
$ tools/perf/trace/beauty/prctl_option.sh > after

That now will be used to decode the syscall option and also to compose
filters, for instance:
