Log Message:
>From OpenBSD...

Fix encoding of DIAG instructions in the MFCPU_T and MTCPU_T macros. MTCPU_T
was encoded as a read instruction, while MFCPU_T was encoded as a
read-through-TH instruction, although the only uses of it concern registers
read through CH.

(You are not supposed to understand this, this is a dark corner of undocumented
rotten PA-RISC bowels).

Cache SID hashing will now correctly be disabled on PCXS, PCXT and PCXT'
processors.

Proper encoding from the old PA-RISC mklinux sources; tested on 720 (PCXS)
and 715/75 (PCXT); ok kettenis@
