It is, mostly. Code committed to the HEAD was slightly modified. Here is 
the patch as it is in SVN:
http://svnweb.freebsd.org/base/head/sys/kern/sched_ule.c?r1=229429&r2=232207&view=patch

And today I've fixed one found bug:
http://svnweb.freebsd.org/base/head/sys/kern/sched_ule.c?r1=232207&r2=232454&view=patch
