| |
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).
The first patch moves prctl and all its helpers into a separate source file, kernel/prctl.c, to allow making it optional via the Makefile without any ifdefs. The second patch adds the Kconfig option to make prctl optional.
Josh Triplett (2): kernel: Move prctl and helpers from kernel/sys.c to new kernel/prctl.c kernel: Support compiling out the prctl syscall
