Modified: sys/kern kern_time.c sys_generic.c
sys/sys kernel.h
sys/ufs/lfs lfs_syscalls.c
Log:
Removed `volatile' from declaration of `time', and removed the resulting
null casts. `time' is nonvolatile for accesses within a region locked
by splclock()/splx(). Accesses outside such a region are invalid, and
splx() must have the side effect of potentially changing all global
variables (since there are hundreds of sort of volatile variables like
`time'), so declaring `time' as volatile didn't have any real benefits.
