are you sure -pg really needs this? I just carried this along the years
and went the path of least resistence, but we should not be
reintroducing the !REGPARM build mode for the kernel. I'd not be
surprised if there were a few issues with REGPARM + mcount, but we have
to figure it out before merging ...
