Author: andrew Date: Sat Aug 17 14:52:19 2013 New Revision: 254451 URL: http://svnweb.freebsd.org/changeset/base/254451 Log: Remove unused FPE code. This is not enabled anywhere as it is the only file I can find containing FAST_FPE. It appears this would not work as want_resched is not defined anywhere.
