Author: nwhitehorn Date: Sun May 4 16:38:21 2014 New Revision: 265329 URL: http://svnweb.freebsd.org/changeset/base/265329 Log: Disable ACPI and P4TCC throttling by default, following discussion on freebsd-current. These CPU speed control techniques are usually unhelpful at best. For now, continue building the relevant code into GENERIC so that it can trivially be re-enabled at runtime if anyone wants it.
