- factor out disksubr.c between sun3, sparc and sparc64. Keep the sun3
groveling code to find a NetBSD disklabel in the first sector (so that it
can find a label at the old sun3 LABELOFFSET) as a fallback is not
label at LABELOFFSET, or sun label is present.
- Fix the sun3 LABELOFFSET (was 64, but the kernel wrote the NetBSD label at
128)
- Make next68k disksubr.c always write a next-compatible disklabel.
- remove #ifdef __sparc__ hack from disklabel(8), and change it to issue
a DIOCWDINFO after writing the disklabel to the raw partition in the
-r/-I case (so that the kernel can convert the label if needed).
* use cd0a rather than cd0[cd] as the CDROM installation device.
This fixes problems with platforms that install from iso9660 images
encapsulated in a partition, and should not affect platforms that
don't.
* add RUN_PROGRESS to the run_prog() flags for ftp installs.

outputting to the files being manipulated by opening a file in the standard IO
descriptor space. In particular, an output file unlucky enough to be sitting
on descriptor 2 (stderr) is certain to be corrupted.
Addresses PR bin/8521, and passes the recently committed regression test

the idle loop. They seem to have gone AWOL sometime in the past.
Fixes port-arm/23390.
- While here, tidy up the idle loop.
- Add a cheap DIAGNOSTIC check for run queue sanity.
returns non-zero and we want to shortcut out. This avoids a bogus pagefault
condition being detected in sa_switch().
Many thanks to Christian Limpach for finding this, obviating my band-aid
patch to kern_sa.c (posted on tech-kern).
the call to data_abort_fixup() as the fixup routines also try to
de-reference the fault pc.
- If a fault came from kernel mode, and the fault address looks to be in
the kernel's address space, and pcb_onfault is *set*, check the
instruction which caused the fault. If it's LDR{B,}T or STR{B,}T
then one of the copy in/out routines is trying to read/write a
kernel address with the wrong privilege. If that address is actually
mapped, we could end up in an infinite loop because we failed to
notice that it's really a 'user mode' access. Yay for "crashme".
I suspect this also fixes PR port-arm/23052.
Note: This *could* be fixed by adding sanity checks to copyin et al,
but that would add extra overhead to the non-error path...
- Fix a couple of __predict_false cases.
This code is not to be reenabled again until it is fixed to my satisfaction
(as a member of core and the person who ends up dealing with most of
the host tool build bugs)
