Applied, thanks!

The argument names used in the prctl wrapper collide with the internal variable names in syscall wrapper macros on some architecture. This currently breaks xtensa. grep for '\b_a[0-9]' indicates that metag and microblaze might also be affected. Prefix argument names with '_prctl' to avoid collision.
