| |
Impact: cleanup
'make headers_check' warn us about leaking of kernel private (mostly compile time vars) data to userspace in headers. Fix it.
sys_arch_prctl is completely removed from header since frankly I don't even understand why we describe it here. It is described like __SYSCALL(__NR_arch_prctl, sys_arch_prctl) in unistd_64.h and implemented in process_64.c. User-mode linux involved? So this one in fact is suspicious.
