Arnaldo Carvalho de Melo 0efc88e444 tools headers UAPI: Sync linux/prctl.h with the kernel sources 
To pick the changes in:

  628d701f2d ("powerpc/dexcr: Add DEXCR prctl interface")
  6b9391b581 ("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
  $ diff -u before after

   	[69] = "RISCV_V_SET_CONTROL",
   	[70] = "RISCV_V_GET_CONTROL",
  +	[71] = "RISCV_SET_ICACHE_FLUSH_CTX",
  +	[72] = "PPC_GET_DEXCR",
  +	[73] = "PPC_SET_DEXCR",
   };
   static const char *prctl_set_mm_options[] = {
   	[1] = "START_CODE",
  $

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

  [root@five ~]# perf trace -e syscalls:sys_enter_prctl --filter option==SET_NAME
       0.000 Isolated Servi/3474327 syscalls:sys_enter_prctl(option: SET_NAME, arg2: 0x7f23f13b7aee)

  ^C[root@five ~]#

This addresses this perf build warning:
