[PATCH] fix vsyscall settimeofday
I've only seen this on x86_64.
The vsyscall state only gets updated when a timer interrupts comes in. So
if the time is set long before the next timer, there will be a period when
a gettimeofday() won't reflect the correct time.
I added an explicit update_vsyscall() during the settimeofday(), that way
the vsyscall state doesn't get stale.
