I'm depending on that patch for a series that gets rid of ARM's
<mach/timex.h>. So I'm interested to either get a stable commit to
base on or alternatively to get the blessing from both of you to take it
(also via arm-soc) as part of my series.

A preview of my series is available at

Best regards
Uwe
