602d8e81f7 Don't (ab)use uvm_map_pageable() to allocate PT pages. Instead, do 
some internal reference counting on PT pages.  We still allocate them
with the page fault routine (a wire-fault, now), but no longer free
PT pages from pmap_pageable().

e33c6c47a2 set bb_flags to zero; who knows what they were (on disk) previously, 
and SRM is finicky about what values it will allow.

b6e1d0f85a set bb_flags to 0. Though not strictly necessary (because of an earlier 
memset()), this is nice for source-level consistency.

c867e93fae Pickup changes from ../biosboot/Makefile and add .PATH so that source

35f356e920 Eliminate more overhead in delay(); there's no point in doing the same 
thing in both the calibrator function and the actual delay function.  At
this point, _delay() does all of the work, so we can garbage collect
dummy_delay() and make _delay() an alternate entry point for delay().

This results in a small (but measurable) improvement on the IIci.

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...

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.

d76e7b8c6d Don't pass a nam2blk around at all; just have setroot() and friends reference

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.
