- Reorganize locking in UVM and provide extra serialisation for pmap(9).
New lock order: [vmpage-owner-lock] -> pmap-lock.
- Simplify locking in some pmap(9) modules by removing P->V locking.
- Use lock object on vmobjlock (and thus vnode_t::v_interlock) to share
the locks amongst UVM objects where necessary (tmpfs, layerfs, unionfs).
- Rewrite and optimise x86 TLB shootdown code, make it simpler and cleaner.
Add TLBSTATS option for x86 to collect statistics about TLB shootdowns.
- Unify /dev/mem et al in MI code and provide required locking (removes
kernel-lock on some ports). Also, avoid cache-aliasing issues.
Thanks to Andrew Doran and Joerg Sonnenberger, as their initial patches
formed the core changes of this branch.

- while here no need to export struct pmap on sun2/sun3/sun3x
No particular problem for a week on hp300 and sun3x kernels with disabled
tcp_vtw which has been broken for a month on low memory machines.
fpu_upd_fpsr() should be called even in discard_result case if an emulated
instruction gets proper result without signal.
Fixes weird behavior of awk(1) seen on /etc/rc.d/postfix on XM6i and
TME emulating sun3 without 68881.
Should be pulled up to all netbsd-4 and netbsd-5 branches.
in db_sym.[ch] as it is used by the elf version of crash(8).
i will be cleaning up the db_sym.c code in a follow up commit to avoid
having dead code compiled.
on all platforms except VAX and IA64. Add fast access via register for
AMD64, i386 and SH3 ports. Use this fast access in libpthread to replace
the stack based pthread_self(). Implement skeleton support for Alpha,
HPPA, PowerPC, SPARC and SPARC64, but leave it disabled.
Ports that support this feature provide __HAVE____LWP_GETPRIVATE_FAST in
machine/types.h and a corresponding __lwp_getprivate_fast in
machine/mcontext.h.
This material is based upon work partially supported by
The NetBSD Foundation under a contract with Joerg Sonnenberger.

Also, merge UCB and Utah copyright texts back into one, as they
originally were.

options EXEC_ELF32, EXEC_SCRIPTS, and CPU_IN_CKSUM for md cpu_in_cksum.c
- make all m68k ports include common arch/m68k/conf/std.m68k
from MD std.${MACHINE}
Based on sys/netinet/cpu_in_cksum.c but just modified
to use traditional MD m68k/oc_cksum.s.
Makes ~5% improvements of ttcp(1) xfer rates on ATARI TT030 + SMC_TT.
appropriately in the kernel config, if not already set.
restores the settings before the M680x0 options became _KERNEL_OPT
options. tested by myself and mhitch.
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.
2. unfortunately hppa's MB_LEN_MAX is defined incorrectly 6 instead of 32
so we have to add more setlocale(3) __RENAME func, __setlocale50.
3. move setlocale1.c and setlocale32.c to lib/libc/compat/locale/*
prepareing for next libc major crunk.
4. bump libc minor version.
M680[12346] are now available from opt_m68k_arch.h. FPSP meantioned
in the PR has already been fixed, and i could not find any more.
i built these kernels to ensure i did not break their builds:
amiga: GENERIC DRACO

mac68k: GENERIC
sun2: GENERIC
sun3: GENERIC GENERIC3X

2. don't typedef void * wc{type,trans}_t, suggested by soda@-san.
it may pass through compiler type check, it's harmful.
so i introduce dummy struct __tag_wc{type,trans}_t(iconv_t already does).
no ABI change was made.
