make process_machdep.c included always since it provides register i/o used by
sys_process_getlwpstatus.c which is always included.

harmonize process_machdep.c inclusion.

Build sh3/sh3/sh3_bus_space.c only for mmeye.

Move some macros back to sh3/include/bus_funcs.h from
sh3/sh3/sh3_machdep.c, where I moved them by mistake.

Pull the bus_space(9) routines into a new module,
sh3/sh3/sh3_bus_space.c, that is built only on !landisk.

Fixes the mmeye and landisk builds.  Should fix other sh3 ports.

Catchup with rmind-uvmplock merge.

Welcome to 5.99.53!  Merge rmind-uvmplock branch:

- 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.

Unify /dev/{mem,kmem,zero,null} implementations in MI code.  Based on patch
from Joerg Sonnenberger, proposed on tech-kern@, in February 2008.

Work and depression still in progress.

Move COMPAT_16 signal stuff to the new compat_16_machdep.c file, so
that it can be built as part of a module.

Make the emulations, exec formats, coredump, NFS, and the NFS server
into modules. By and large this commit:

- shuffles header files and ifdefs
- splits code out where necessary to be modular
- adds module glue for each of the components
- adds/replaces hooks for things that can be installed at runtime

Add cpu_in_cksum.S

Catch up with "Refactor in_cksum/in4_cksum/in6_cksum implementations".

Refactor in_cksum/in4_cksum/in6_cksum implementations:
- All three functions are included in the kernel by default.
  They call a backend function cpu_in_cksum after possibly
  computing the checksum of the pseudo header.
- cpu_in_cksum is the core to implement the one-complement sum.
  The default implementation is moderate fast on most platforms
  and provides a 32bit accumulator with 16bit addends for L32 platforms
  and a 64bit accumulator with 32bit addends for L64 platforms.
  It handles edge cases like very large mbuf chains (could happen with
  native IPv6 in the future) and provides a good base for new native
  implementations.
- Modify i386 and amd64 assembly to use the new interface.

This disables the MD implementations on !x86 until the conversion is
done. For Alpha, the portable version is faster.

Merge the ppcoea-renovation branch to HEAD.

This branch was a major cleanup and rototill of many of the various OEA
cpu based PPC ports that focused on sharing as much code as possible
between the various ports to eliminate near-identical copies of files in
every tree.  Additionally there is a new PIC system that unifies the
interface to interrupt code for all different OEA ppc arches.  The work
for this branch was done by a variety of people, too long to list here.

TODO:
bebox still needs work to complete the transition to -renovation.
ofppc still needs a bunch of work, which I will be looking at.
ev64260 still needs to be renovated
amigappc was not attempted.

NOTES:
pmppc was removed as an arch, and moved to a evbppc target.

Since everyone uses clock_subr.c (or should, if they don't currently),
list it in conf/files instead of in every port's files.*.

rename Locore.c -> locore_c.c so that we can compile on case insensitive
filesystems. (from John Gordon)

catch up with -current on kqueue branch

remove COMPAT_13 staff. No 1.3 release of sh3 port. these are trace of
i386 port.

file files.sh3 was added on branch nathanw_sa on 2002-05-10 15:25:14 +0000

remove COMPAT_13 staff. No 1.3 release of sh3 port. these are trace of
i386 port.

rework general exception, and TLB exception handling for new pmap.
all exception staffs are moved to exception.[ch]

* Defflag the SH3 and SH4 options.
* In <sh3/cputypes.h>, always define both SH3 and SH4 if _LKM is defined.

All the sh3 ports had an identical procfs_machdep.c, so use a common
file under arch/sh3/sh3.

Rework interrupt code.
 + Fully utilize SH SR.I[0:3] interrupt level.
 + software interrupt is emulated by TMU1, 2 one shot interrupt.
 + implement generic soft interrupts.
 + implement clockframe correctly.

cosmetic changes, fix comments.

add kernel stack debug option.

Catch up with -current.

Initial support for KGDB on the sh3.

Cleanup register definition

Move common exception vector and scheduler code to
sh3/sh3/exception_vector.S and sh3/sh3/locore_subr.S. exception
vectors are installed by sh_cpu_init().  machine/locore.S contains
kernel entry, interrupt handler, and some MD code.

NetBSD/sh3 common part of clock routine.

Clean up functions
disable_intr, enable_intr, disable_interrupt, enable_interrupt,
disable_ext_intr, enable_ext_intr.
New functions:
for external interrupt:
_cpu_intr_suspend and _cpu_intr_resume.
for exception:
_cpu_exception_suspend and _cpu_exception_resume.

Add new MMU API.  for detail, see sh3/mmu.h's comment.

add new cache routine.

Sync kqueue branch with -current.

- replace "defopt" with "defparam" for options which must take a value,
  as config(8) will warn for value-less defparam options
- minor whitespace/formatting cleanup
- consolidate opt_tcp_recvspace.h and opt_tcp_sendspace.h into opt_tcp_space.h

Merge Aug 24 -current into the kqueue branch.

Sync with HEAD.

move machine-port specific file to machine directory.
for evbsh3, mmeye and dreamcast, use MI md_root.c

Update thorpej_scsipi to -current as of a month ago
A i386 GENERIC kernel compiles without the siop, ahc and bha drivers
(will be updated later). i386 IDE/ATAPI and ncr work, as well as
sparc/esp_sbus. alpha should work as well (untested yet).
siop, ahc and bha will be updated once I've updated the branch to current
-current, as well as machine-dependant code.

Disassembly support in DDB.

Switch to MI ns_cksum.c - the MD ns_cksum.c is equivalent to it
(modulo some u_intX_t vs. u_char type usage). In particular, the
MD version didn't contain any MD code.

Allow arch-specific code to specify in4_cksum() like it can specify
in_cksum().

use clock_subr.c

in_cksum.c ->in_cksum.S

Move common parts of machdep.c to sh3_machdep.c.

Merge in NetBSD/sh3 from cvs.kame.net repository.

Tree structure:
- sys/arch/sh3: sh3 generic code
	As commented, in-chip device drivers are put into sys/arch/sh3/dev.
- sys/arch/evbsh3: sh3 evaluation boards (pure sh3 CPU, no fancy external HW)
- sys/arch/mmeye: Brains mmEye, www.brains.co.jp
MI source code includes couple of #ifdef for sh3-coff support.
(sh3 uses coff or elf)

Needs some more improvements, especialy in sys/arch/sh3/conf/files.sh3,
to compile the tree (due to last minute tree structure change).
