move DEV_BSIZE, DEV_BSHIFT out of MD param.h, they are same on all ports

also move BLKDEV_IOSIZE, MAXPHYS, but allow override since some ports
have different value (powerpc uses NBPG for BLKDEV_IOSIZE, sun2/sun3
have lower MAXPHYS)

branches: 1.45.54;
- include <mips/mips_param.h> after MACHINE is defined
- remove redundant comment

Now that MACHINE is defined in user-land in either
mips/include/mips_param.h or powerpc/include/param.h, stop
trying to re-define it in the port-specific param.h files
when _KERNEL isn't defined.

Merge forward from matt-nb5-mips64.
New interrupt code.
mips64 support for DS5000/260.

Remove clause 3 (UCB advertising clause) from the University of Utah
copyright. Confirmed by Mike Hibler, mike at cs.utah.edu - thanks!
Also, merge UCB and Utah copyright texts back into one, as they
originally were.

Extra verification by snj@.

Merge from matt-nb5-mips64
Merge mips-specific arch files.

Move MID_MACHINE to <mips/mips_param.h> and use local values so we don't
need to include exec_aout.h

Remove all the __P() from sys (excluding sys/dist)
Diff checked with grep and MK1 eyeball.
i386 and amd64 GENERIC and sys still build.

Change dumb DELAY(9) macro into inline version with asm like
other mips ports for gcc4's aggressive optimization.

merge ktrace-lwp.

Move UCB-licensed code from 4-clause to 3-clause licence.

Patches provided by Joel Baker in PR 22364, verified by myself.

Purge CLSIZE, CLSIZELOG2 and MCLOFSET.
Be consistant in the way that MSIZE, MCLSHIFT, MCLBYTES and NMBCLUSTERS
are defined.
Remove old VM constants from cesfic port.
Bump MSIZE to 256 on mipsco (the only one that wasn't already 256).

branches: 1.34.2; 1.34.8;
use _KERNEL_OPT

branches: 1.33.2;
raise MSIZE from 128 to 256.
- for sizeof(void *) == 8 arch, this is mandatory. MHLEN is too small
already (less than 80) and there are chances for unwanted packet loss due
to m_pullup restriction.
- for other cases, the change should avoid allocating clusters in most cases
(even when you have IPv4 IPsec tunnel, or IPv6 with moderate amount of
extension header)

portmasters: if your arch chokes with the change (high memory usage or
whatever), please backout the change for your arch.

branches: 1.32.4;
- Remove three unused contants; KERNBASE, KERNTEXTOFF and BTOPKERNBASE.
- Protect #include <machine/intr.h> inclusion with #ifdef _KERNEL.
- Correct the case when "opt_gateway.h" is refered.

Nuke register.

- Fix RCS Ids.
- Spacing.
- Protect from multiple inclusion in a consistant way (except on headers
that do nothing except function as mips header wrappers).

Function prototype cleanup.

CL* discarding.

branches: 1.27.8; 1.27.14;
Split the "mips" MACHINE_ARCH for 1.4. newsmips is "mipseb"; pmax is
"mipsel".

branches: 1.26.2;
Make spl(9) rountines target port dependent. delay() is also port
dependent anticipating a target with high resolution timer available
for on-the-fly re-programming. Enum decstation_t was removed from MI
trap.c.

Pull in opt_gateway.h as appropriate.

Move the definition of MSGBUFSIZE up to the machine-arch level if
possible. Pointed out by Bernd Ernesti.

Implement the kernel part of pr-1891. This allows for a more flexible sized
msgbuf. Note that old 'dmesg' and 'syslogd' binaries will continue running,
though old 'dmesg' binaries will output a few bytes of junk at the start of
the buffer, and will miss a few bytes at the end of the buffer.

Move SSIZE and DELAY() definitions to sys/arch/mips/include/mips_param.h.
Update comment in pmax/include/param.h (pr 3988).

branches: 1.21.2;
DDB for mips.
Add DDB interface to /sys/arch/mips/mips..
Rework heuristic stack traceback to work with DDB.
Add hooks to print exception log from DDB.
Add hooks from pmax console drivers: call Debugger()
after break from serial console, or 'DO' key from LK-xxx.

More merged MIPS1/MIPS3 support for DECstations.

Move MACHINE_ARCH and _MACHINE_ARCH from pmax/include/param.h to
mips/include/mips_param.h. (They should be common to all mips ports.)

Protect MCLSHIFT definition so users can customize MCLBYTES.
Also define MCLBYTES from MCLSHIFT.

branches: 1.17.8;
Fix typo in NMBCLUSTERS definition.

Remove common-across-all-MIPS-cpu definitions (e.g., user-level-visible
page/segment size definitions and macros) and move them to
mips/include/mips_param.h.

add _MACHINE and _MACHINE_ARCH, which are like MACHINE and MACHINE_ARCH,
execpt without quotes. meant to be __CONCAT()ted for easy #includes
of machine-dependent headers for MI code (e.g. for the MI ISA/EISA/PCI/TC
bus code).

Clean up tabbing/spacing in defns of MACHINE, MACHINE_ARCH, and MID_MACHINE.

LOCORE -> _LOCORE

Add argument prototypes - __P((void)) - to the declarations of Mach_spl*() functions.

kill user-land DELAY macro, as suggested by gwr.

clean up definitions of ctod(), dtoc(), ctob(), btoc(), btodb(), and
dbtob(). remove unused definitions of ctos(), stoc(), and dtob().

KERNEL -> _KERNEL

don't be so quick to cast macro arguments to unsigned; if the
arguments are really off_t's (e.g. to btodb), then you can lose
information. This was the "> 4G file systems don't work" bug; physio
uses btodb, which was broken.

fix from Jonathan Stone

new RCS ID format.

add USPACE

bsd 4.4-lite pmax port as ported to NetBSD

upgrade to bsd 4.4-lite code base. only mod is rcsids

some pmax updating (Terry Friedrichsen is helping on this now).
