patches 1 and 3 apply on top of tip:core/timer

patch 2 also requires Richards ptp v12 1/4 for the ptp class.
modulo a small conflict in drivers/ptp/Makefile and Kconfig.
because i had added his ixp driver, which the software clock is based on.

Richards Patchset didnt apply to tip:core/timer as is.
which branch is it based on ?
