21a8b350dc Don't conditionally define CACHE_LINE_SHIFT, as we anticipate sizing
a fair number of static data structures, making this an unlikely
option to try to change without also changing source code. [1]

Change default cache line size on ia64, sparc64, and sun4v to 128
bytes, as this was what rtld-elf was already using on those
platforms. [2]

8df790f38f For each architecture, define CACHE_LINE_SHIFT and a derived
CACHE_LINE_SIZE constant.  These constants are intended to
over-estimate the cache line size, and be used at compile-time
when a run-time tuning alternative isn't appropriate or
available.

Defaults for all architectures are 64 bytes, except powerpc
where it is 128 bytes (used on G5 systems).

Follow one of the two most common indent schemes in this file.

7695aca762 Add AT_EXECPATH ELF auxinfo entry type. The value's a_ptr is a pointer
to the full path of the image that is being executed.
Increase AT_COUNT.

Remove no longer true comment about types used in Linux ELF binaries,
listed types contain FreeBSD-specific entries.

2d3842287a MFp4:
- Add debug output
- Fix pmap_zero_page and related places: use uncached segments and invalidate
    cache after zeroing memory.
- Do not test for modified bit if it's not neccessary
    (merged from mips-juniper p4 branch)
- Some #includes reorganization

a69ce4ce83 Start to clean up the MIPS elf machine dependent file.
o Add support for compiling elf64 for this file (the rest of the changes are
  coming later)
o Fill in some misssing relocation types.  We need to support these in
  elf_machdep.c's relocation routines eventually, but that's future work
  too.

954d43d968 Catch up with svn r96606 (cvs rev 1.127 2002/05/14 20:35:29) of
sys/param.h and move the MI numbers out of here.  Also move the MI
defines.  Also remove a couple defines not in use (not sure if it is
age, or OpenBSD origins for thse).  Note the current values that are
overrides that appear to be odd in some way.

More cleanup could be done here: NBPG appears to be spelled PAGE_SIZE
these days.  There's new ways to spell PGOFSET and PGSHIFT too, I
think.  These constants duplicate the MI constants and are sprinkled
into the mips code only.  Further investigation is needed.

a1ec700ce8 Remove ipi_all() and ipi_self() as the former hasn't been used at
all to date and the latter also is only used in ia64 and powerpc
code which no longer serves a real purpose after bring-up and just
can be removed as well. Note that architectures like sun4u also
provide no means of implementing IPI'ing a CPU itself natively
in the first place.

4d6a9685e8 Remove the unused major/minor numbers from iodev and memdev.
Now that st_rdev is being automatically generated by the kernel, there
is no need to define static major/minor numbers for the iodev and
memdev. We still need the minor numbers for the memdev, however, to
distinguish between /dev/mem and /dev/kmem.

352e51d169 FreeBSD/mips port. The FreeBSD/mips port targets mips32, mips64,
mips32r2 and mips64r2 (and close relatives) processors.  There
presently is support for ADMtek ADM5120, A mips 4Kc in a malta board,
the RB533 routerboard (based on IDT RC32434) and some preliminary
support for sibtye/broadcom designs.  Other hardware support will be
forthcomcing.

This port boots multiuser under gxemul emulating the malta board and
also bootstraps on the hardware whose support is forthcoming...

Oleksandr Tymoshenko, Wojciech Koszek, Warner Losh, Olivier Houchard,
Randall Stewert and others that have contributed to the mips2 and/or
mips2-jnpr perforce branches.  Juniper contirbuted a generic mips port
late in the life cycle of the misp2 branch.  Warner Losh merged the
mips2 and Juniper code bases, and others list above have worked for
the past several months to get to multiuser.

In addition, the mips2 work owe a debt to the trail blazing efforts of
the original mips branch in perforce done by Juli Mallett.
