Author: jhb Date: Fri Feb 4 14:44:59 2011 New Revision: 218277 URL: http://svn.freebsd.org/changeset/base/218277 Log: MFC 217075: Retire PCONFIG and leave the priority of thread0 alone when waiting for interrupt config hooks to execute. To preserve the KBI, I did not renumber priorities but simply removed PCONFIG.
