One note: Many MIPS32 implementations choose not to implement all 36 PA
bits, but limit themselves to 32 bits. This saves a few bits in the TLB
and a few address lines.

So, if someone did want 36 PA bits on Linux, the TLB exception handlers
and a little of the page table construction/management code would have to
change. The userspace contraints and such would still remain. Cool.

Basically the whole code is already in place except a few bugs fixes that
still need to go in.
