src/sys/kern: subr_time.c
Log Message:
fix and cleanup for tvtohz():
-assume (KASSERT) that the timeval given is normalized, and remove
some partial fixup which I don't see what it is good for
(I'm ready to back that out if someone tells a reason)
-catch overflows due to conversion of time_t (from tv_sec) to
integer -- this function doesn't do 64-bit arithmetics (which makes
sense because relative times which don't fit into 32 bits can be
considered nonsense here), and before a huge tv_sec could lead to
a zero hz result, violating the caller's assumptions (in particular
trigger a diagnostic panic in abstimeout2timo())
