[PATCH] hpet: fix drift and url
The HPET driver is using a parts per second drift factor instead of the standard parts per million drift the time interpolator code expects. This patch fixes that problem and updates the URL for the HPET spec. Signed-off-by: Alex Williamson <alex.williamson@hp.com> Cc: "Robert W.
