f2f8426e86 Write a new low-level assembly help for delay() and the calibrator. This 
eliminates stalls during instruction prefetch and makes the delay
consistent regardless of kernel configuration.

b7a2ec3f01 + Call prom_scsiid() to found out what the host SCSI ID should 
be instead of hardcoding values.
 + Print the host SCSI ID in siiattach().

XXX - probably should do the same to the ASC driver??  The manuals for
the 5000 series machines don't mention the scsiidN env variable, but it
is present on all the models I've looked at...

84380f9fbe In sosend(), if so_error is set, clear it before returning the error to 
the process (i.e. pre-Reno behavior).  The 4.4BSD behavior (introduced
in Reno) caused transient errors to stick incorrectly.

This is from PR #7640 (Havard Eidnes), cross-checked w/ FreeBSD, where
Bill Fenner committed the same fix (as described in a comment in the
Vat sources, by Van Jacobsen).

540b02ab76 - Exterminate haunted evil soul of MIPS va_arg(). Verified OK with 
either endian.  Not a perfect solution which would be revealed on
a certain condition when va_arg() is applied to magical struct
arguments passed by value.  format_bytes() is now saved.  With the
help from Noriyuki Soda and Masanari Tsubai.

b7ee76f1c4 Check for an unterminated bus; if yes: complain and don't try to use this 
bus. Without this, cbiiisc used to hang if nothing was connected.
Reported by Matthias Scheler. A similar method to avoid this was suggested
by Ralph Schmidt.

1884f05354 Another general cleanup: 
Remove the entire idea of fasttrap interrupts since V9 traps are really cheap,
the CPUs are really fast, and the completely different trap frames would make
these handlers really difficult to implement.

pmap_changeprot() was only used by the clock and one other place; deprecate it.

probeget() and probeset() now take 64-bit addresses even in 32-bit mode so we
can probe IO locations by physical addresses.

Some pmap cleanup.

Some more copyright cleanup.
