First of all, the unification looks good.

As far as .32 is concerned... this *is* a bug even if this is only for
paravirt, and given the small amount of code I am personally OK with
taking the whole patch for .32.

However, the patch is not complete!  The patch incidentally eliminates
the need to have assembly stubs for sys_iopl, and those assembly stubs
should be removed.  I have a patch for that currently test building.
