What does that have to do with anything? Adding fuptr()/suptr()
has no consequences for supporting or not supporting different
memory models with different pointer sizes. The functions are
defined to operate on native (kernel PoV) pointers. Any non-
native (kernel PoV) ABI has a non-native ABI handler that does
all the mapping, converting and copying bits from userland to
kernel and vice versa.

And I can't believe I actually wasted my time telling you this
when you only have to use your head instead of your keyboard.
