* sysdeps/unix/sysv/linux/clock_gettime.c (SYSDEP_GETTIME_CPU)
[__ASSUME_POSIX_CPU_TIMERS > 0]: Assign to retval and break.
* sysdeps/unix/sysv/linux/x86_64/clock_gettime.c
(SYSCALL_GETTIME): Set errno on error.
* sysdeps/unix/sysv/linux/check_pf.c (make_request): Properly
count references to noai6ai_cached.
