At the very least the kernel/auditsc.c file still makes use of the
timespec64 struct which is defined in include/linux/time64.h which is
brought in by include/linux/time.h and *not* by
include/linux/timekeeping.h.  As long as we make use of the timespec64
struct and the definition remains in time64.h let's keep the time.h
include.
