PERFORCE change 135760 for review

[M. Warner Losh]

	Suppress the aggressive inline of gcc; there is no obvious
	benefit to doing it and the downsides are significant.  Once
	I can nagivate the maze of twisty #ifdefs in cdefs.h I'll
	add __noinline where it belongs.

Maybe the following is sufficient?
