[PATCH 2/2] kernel: Support compiling out the prctl syscall

2016-11-08 Thread Josh Triplett
Some embedded systems can do without the prctl syscall, saving some space. This also avoids regular increases in tinyconfig size as people add more non-optional functionality to prctl (observed via the 0-day kernel infrastructure). bloat-o-meter results: add/remove: 0/3 grow/shrink: 0/1 up/down:
