May I humbly ask why the [Finnish] you don't use the equivalent of the
x86 _ASM_EXTABLE() macro?  In fact, why don't we make that one generic, too?

I'm messing with that right now (with help from Andy Lutomirski and Boris) to
add different classes of exception table (so I can tag some instructions as being
suitable for fixup from the machine check handler).  So it might not be generic
for much longer.
