[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.
