Jeez, thanks for finding that.

I don't think it should, unless you're profiling.  The problem is that -pg
and regparam(3) don't (or didn't) interact nicely.  The -pg code trashed
the arguments that regparam was passing in registers, and you'd get strange
panics early in boot.

Have you checked that this actually fixes anything?  It looks like just a 
stupid typo to me.
