dc306354b0 Move the bswap functions from libutil to libc (this bups the 
minor of libc and the major of libutil). For little-endian architectures
merge the bnswap() assembly versions with nto* and hton* using symbols
aliasing. Use symbol renaming for the bswap function in this case to avoid
namespace pollution.
Declare bswap* in machine/bswap.h, not machine/endian.h. For little-endian
machines, common code for inline macros go in machine/byte_swap.h
Sync libkern with libc.
Adjust #include in kernel sources for machine/bswap.h.

008816ea4f Changes to sys/arch/mips from ARC port, from Noriyuki Soda <soda@sra.co.jp>. 
Adds (most) support for ARC platform to port-independent mips code.

Some changes (e.g., clean up of overlapping CPU/FPU ids) inspired by
comparison to the OpenBSD 2.1 codebase of Soda's ARC port.

Open issues:
 * Still no support for r4600 or mipsIV CPUs with two-way L1 cache.
   Code derived from Per Fogelstrom's OpenBSD source  doesn't work
   on mips3 pmaxes with L2 cache.

 * Still some port-specific  #ifdefs, for interrupt enable and
   pmax L2 cache-size.  Needs more thought, but overlaps with
   work-in-progress by Tohru and Tsubai on spl()s and related stuff.

1a8c7604f4 initial import of the new virtual memory system, UVM, into -current. 
UVM was written by chuck cranor <chuck@maria.wustl.edu>, with some
minor portions derived from the old Mach code.  i provided some help
getting swap and paging working, and other bug fixes/ideas.  chuck
silvers <chuq@chuq.com> also provided some other fixes.

this is the rest of the MI portion changes.

this will be KNF'd shortly.  :-)

4369378a6c add rules like those in libc to build strchr() and strrchr() (the latter 
is being added to libkern by this commit).  remove strchr.c from
archs' Makefile.inc files to go along with this.  (If an arch has
a .S version, it should be copied down and added to the apropriate
Makefile.inc.)

bdbfa48c0b Add machine-independent assertion-checking support. macros are: 
assert()	which always does assertion checking
			unless "NDEBUG" is defined.

	KASSERT()	which does assertion checking if DIAGNOSTIC
			is defined.

	KDASSERT()	which does assertion checking if DEBUG is
			define.  This macro exists for compatibility
			with existing ports' assertion checking macros.
			(Assertion checking is not typically an
			"expensive" operation, and DIAGNOSTIC should be
			used for inexpensive consistency checks.)

this case adosfs).  (There are several arguments that say that
strncasecmp should not be in libkern at all, and i think they're
good ones, but as long as ADOSFS needs it to link, it has to be here
for all architectures.)

606d45ee4a Move the SRCS from hp300 over to here, changing ffs.c to ffs.s. 
Am I missing something obvious in doing this?  This makes the
${ARCH}/Makefile.inc for 68k able to just set ARCH=m68k.

e685fd393f added files copied in from libc. version numbers are screwed, 
but are screwed for the rest of libkern's files, anyway.

823c36577c Change instances of LIBC_RCS back to LIBC_SCCS. If we are going to change 
th LIBC_RCS, the entire source tree should be updated at once.
Remove && !defined(lint) from conditionals around rcs id's.  No one is
ever going to pass a *.s file through lint.

97ad548bc0 Replaced instructions with immediate operands with compatible alternatives 
saving a few bytes while the cycle count remains the same --- could
actually be faster, depending on the cache, prefetch queue, etc.
