will have unimplemented services showing their names in ktrace
Add a new generated file with only service id and name, which will
be included by kdump to display services names.
This removes the need for using the user ktrace facility for services names.
- 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.
