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.
