>Description:

	The below patch, will close PR docs/32825, and also documents
	the PFIL_HOOKS option, which is currently undocumented.  The
	PFIL_HOOKS definition was provided on the cvs-all@ and the 
	cvs-committers@ list, by cjc@ and Darren Reed.

	I suggest keeping this PR open, as I have some more options
	in the NOTES file to document.  Probably the patches can be
	applied and a follow-up can be sent acknowledging the PR, but
	not closing it. :)

>How-To-Repeat:
	n/a
>Fix:

	(kindly) Apply this patch to src/sys/i386/conf/NOTES.
