x86: Remove now-unused
In OMAP5 when USB-HOST is set true, the VBUS regulator is turned ON.

There is a redundant call for timer_stats_timer_set_start_info(),
because it is the responsibility of the 'timer add' function:

the one nouveau fix is for a regression I caused with the poweroff stuff.

In OMAP5 when USB-HOST is set true, the VBUS regulator is turned ON.
This causes a VBUS interrupt, ignore the same if we are already in
USB-HOST.

Hi.
At the bottom of the description of the patch set, i warn about the
latencies and jitter.
I did real test with a pps generated by a workstation (i haven't
tested with a precise pps yet), so the the jitter don't mean anything.
But the magnitude of difference between uart and usb pps
