Hmm, I indeed missed some uses, i.e. ep93xx, mmp, netx, sa1100, u300,
ixp4xx and rpc use CLOCK_TICK_RATE (or LATCH). Also
drivers/rtc/rtc-pxa.c uses CLOCK_TICK_RATE. I didn't find that
ARCH_USES_GETTIMEOFFSET implies a use of CLOCK_TICK_RATE though. Did I
miss something?

For now I took the patch out of my next branch and will rework it to at
least let the above listed platforms also continue to use timex.h.

Best regards
Uwe
