Maybe I'm being thick, but...  if we're rendering these addresses
unusable by hashing them, why not just print something like
"<obscured>" in their place?  That loses the uniqueness thing but I
wonder how valuable that is in practice?

My worry is that is you get a kernel 'oops' print with actual register
values you have no easy way of tying an address or address+offset to
the corresponding hash(address) printed elsewhere.

print the existing hash:pointer mappings in panic()? [if we can do that]

by this I meant
	"when oops_in_progress == 1 then print hash:pointer for %p,
	 not just hash".
