add new prctl command PR_SET_MM_MAP to sys/prctl.h
PR_SET_MM_MAP was introduced as a subcommand for PR_SET_MM in linux v3.18 commit f606b77f1a9e362451aca8f81d8f36a3a112139e the associated struct type is replicated in sys/prctl.h using libc types. example usage: struct prctl_mm_map *p; ... prctl(PR_SET_MM, PR_SET_MM_MAP, p, sizeof *p); the kernel side supported struct size may be queried with the PR_SET_MM_MAP_SIZE subcommand.
