#     posix-timers: Get rid of [COMPAT_]SYS_NI() uses
#     
#     Only the posix timer system calls use this (when the posix timer support
#     is disabled, which does not actually happen in any normal case), because
#     they had debug code to print out a warning about missing system calls.
#     
#     Get rid of that special case, and just use the standard COND_SYSCALL
#     interface that creates weak system call stubs that return -ENOSYS for
#     when the system call does not exist.
#     
#     This fixes a kCFI issue with the SYS_NI() hackery:
#     
#       CFI failure at int80_emulation+0x67/0xb0 (target: sys_ni_posix_timers+0x0/0x70; expected type: 0xb02b34d9)
#       WARNING: CPU: 0 PID: 48 at int80_emulation+0x67/0xb0
