3.2-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jacob Keller <jacob.e.kel...@intel.com>
commit 87f4d7c1d36f44b0822053b7e5dedc31fdd0ab99 upstream.
This patch updates the adjfreq callback description to include a note that the
delta in ppb is always relative to the base frequency, and not to the current
frequency of the hardware clock.
