So, my theory was half right.  It was a problem with 64-bit mtsr
emulation, but it wasn't that I just removed that code with the SLB
cleanup.  The code was still there and *almost* right.  I was off by
one in one shift, causing the storage key bits to end up in the wrong
place in the SLB entry.  I'll send out the patch right after I've sent
this mail.
