This patch does the following:

Pushs down the change from timeval to timespec in the settime routines.

Fixes two places where time was set without updating the monotonic 
clock offset.  (Changes sys_stime() to call do_settimeofday() and 
changes clock_warp to do the update directly.)  These were bugs!

Changes the uptime code to use the posix_clock_monotonic notion of 
uptime instead of the jiffies.  This time will track NTP changes and 
so should be better than your standard wristwatch (if your using ntp).

Changes posix_clock_monotonic to start at 0 on boot (was set to start 
at initial jiffies).

Adds a test in do_settimeofday() to error out (EINVAL) attempts to use 
unnormalized times.  This is passed back up to both settimeofday and 
posix_setclock().

Warning: Requires changes in .../arch/???/kernel/time.c to change 
do_settimeofday() to return an error if time is not normalized and to 
use a timespec instead of timeval for its input.
