a5e696e5d0 MIPS: 64-bit: Fix system lockup.
The address range size calculation inside local_flush_tlb_kernel_range()
is being truncated by a too small size variable holder on 64-bit systems.
The truncated size can result in an erroneous tlbsize check that means we
sit spinning inside a loop trying to flush a hige number of TLB entries.
This is for all intents and purposes a system hang. Fix by using an
appropriately sized valiable to hold the size.

[Ralf: Greg's original patch submission identified the issue and fixed one
instance in tlb-r4k.c but there there were several more.  For consistency
I also modified tlb-r3k.c even though that file is only used on 32-bit.]

af6dc22b03 [MIPS] tlb-r4k: Nuke broken paranoia error test.
Bug originally found and reported by Julia Lawall <julia@diku.dk>.  I
decieded that the whole error check was mostly useless paranoia and should
be discarded.  It would only ever trigger if r3k_have_wired_reg has a wrong
value.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
