Modified files:
sys/kern : kern_exec.c
sys/sys : proc.h
Log message:
Add PS_NOBTCFI, a per-process flag indicating that Branch Target
Control Flow Integrity has been disabled for the process. At
exec-time, set that flag iff EXEC_NOBTCFI is passed from the ELF
exec bits (which set it based on presence of a PT_OPENBSD_NOBTCFI
segment). This will be used by the amd64 code.
