reworked by me to support 32-bit processes as well.
we now keep %fs and %gs loaded with the user values
while in the kernel, which means we don't need to
reload them when returning to user mode.
move the "old" value to %*ax so that cmpxchg* can work.
remove the PCB_ONFAULT stuff, onfault_handler() handles this already.
return the error from fault handler in ucas_fault rather than forcing EFAULT.
Add MI flags PMAP_WRITE_COMBINE, PMAP_WRITE_BACK, PMAP_NOCACHE_OVR.
Update pmap(9) manpage.
hppa: Remove MD PMAP_NOCACHE flag as it exists as MI flag
mips: Rename MD PMAP_NOCACHE to PGC_NOCACHE.
x86: Implement new MI flags using Page-Attribute Tables.
x86: Implement BUS_SPACE_MAP_PREFETCHABLE.

No comments on this last version.
we're ELF now, and there are many missing checks against OBJECT_FMT.
if we ever consider switching, the we can figure out what new ones
we need but for now it's just clutter.
this doesn't remove any of the support for exec_aout or any actually
required-for-boot a.out support, only the ability to build a netbsd
release in a.out format. ie, most of this code has been dead for
over a decade.
i've tested builds on vax, amd64, i386, mac68k, macppc, sparc, atari,
amiga, shark, cats, dreamcast, landisk, mmeye and x68k. this covers
the 5 MACHINE_ARCH's affected, and all the other arch code touched.
it also includes some actual run-time testing of sparc, i386 and
shark, and i performed binary comparison upon amiga and x68k as well.
some minor details relevant:
- move shlib.[ch] from ld.aout_so into ldconfig proper, and cut them
down to only the parts ldconfig needs
- remove various unused source files
- switch amiga bootblocks to using elf2bb.h instead of aout2bb.h
Rename real routines to proc_find() and pgrp_find(), remove PFIND_* flags
and have consistent behaviour. Provide proc_find_raw() for special cases.
Fix memory leak in sysctl_proc_corename().
COMPAT_LINUX: rework ptrace() locking, minimise differences between
different versions per-arch.
Note: while this change adds some formal cosmetics for COMPAT_DARWIN and
COMPAT_IRIX - locking there is utterly broken (for ages).
Fixes PR/43176.
instruction to calculate a relative branch target address from that
instruction.
Not sure what the intention of this change was, or if it could possibly
have been tested.
Fixes awk on my dbau1500.

Establish interrupt handlers with proper softc per each zs device
rather than sharing them among all zs devices and searching softc
in handlers, to avoid possible recursive lock.

The latter method is derived from ancient sun3 zs driver which tried
to reduce overhead on autovectored interrupts, but nowadays such hack
might cause recursive global locks on modern SMP capable framework.

by hpcboot.exe as well as other hpc* ports. Noticed by uwe@.
Also comment out options RTC_OFFSET=0 lines and note about this
in kernel config files. Tested on WS003SH.
