@ -335,3 +335,12 @@ Why: In 2.6.18 the Secmark concept was introduced to replace the "compat_net"
Secmark, it is time to deprecate the older mechanism and start the
process of removing the old code.
Who: Paul Moore <paul.moore@hp.com>
---------------------------
What: sysfs ui for changing p4-clockmod parameters
When: September 2009
Why: See commits 129f8ae9b1b5be94517da76009ea956e89104ce8 and
e088e4c9cdb618675874becb91b2fd581ee707e6.
Removal is subject to fixing any remaining bugs in ACPI which may
cause the thermal throttling not to happen at the right time.
