The linux kernel already provides a hash function. Let's reuse that
instead of reinventing the wheel!

Initially we had to search for pte entries to invalidate them. Since
the logic has improved since then, we can just get rid of the search
function.

For KVM we need to find the location of the HTAB. We can either rely
on internal data structures of the kernel or ask the hardware.
Ben issued complaints about the internal data structure method, so
let's switch it to our own inquiry of the HTAB. Now we're fully
independend :-).

There are some pieces in the code that I overlooked that still use
u64s instead of longs. This slows down 32 bit hosts unnecessarily, so
let's just move them to ulong.

In order to support 32 bit Book3S, we need to add code to enable our
shadow MMU to actually add shadow PTEs. This is the module enabling
that support.
