This is a mismerge/mis-rebase of one of my patches actually. I'll dbl
check what's up but I think the first hunk should go along with
LMB_REAL_LIMIT in favor of the new default limit thing. But we first
need to make sure the default is set sensibly and I haven't fixed all
archs yet.

I'll dbl check what's up there.

Cheers,
