part. Some ports can optimize the swap operations. This also means the
general API is extended with swap16, swap32, htobe16, htobe32, betoh16,
betoh32, htole16, htole32, letoh16 and letoh32.

Rename auxreg.h because we need config to generate one now.

reference for making transferral of meta-information possible from
readdisklabel to bounds_check_with_label. The first (and maybe only)
thing that will use this is the multi-disklabel-format code on the
alpha where the labelsector is passed via cpu_disklabel so the label
write-protection can work correctly no matter what label was found.
Also use a new macro DKBAD to get at the dkbad field of the cpu_disklabel
implementations that contain it. This too is for multi-disklabel
architectures where the "bad" field can be inside a union. Use this
macro as a means for a driver to check if an architecture supports
dkbad constructs.
Remove proto of bounds_check_with_label from all MD disklabel.h as it
is in sys/disklabel.h.
I have not been able to test the changes everywhere, if I break anything
I apologize, and promise to fix it as soon as I become aware of it.

GENERIC currently compiles and runs; some devices (isp) are not complete and
not yet enabled.

Add options NETATALK to your config to try it out.

supposedly adds additional instruction scheduling for better performance,
where -mv8 seems to only "allow" the multiply and div instructions. This
is what I got from the gcc docs anyway.. Reading the RTL for sparc seems
to agree with this hypothesis, and the man pages..

failures in innocent programs. Typically something like a make build
of libc or something executing a large number of shell commands would
fail, dumping core in sh or random faults in as or cc*.
According to Chris Torek, the problem is that he make the destination
pages for zero and copy be non-cached to prevent wiping otherwise
relevant stuff from the cache.
On systems with a L2 cache like the SS10 modules with cache, setting
the pages as non-cacheable inhibits updating the chache, and also
disable PA chache snooping, doesn't do anything about possible dirty
lines in the L2 cache, which may eventually get flushed and corrupt the
nice new page.
It's not clear that he's got the failure mode 100% correct, but making
the pages cacheable does seem to avoid the symptoms and testing the
e-cache flush hypothesis is difficult.
Aaron Brown proposed a fix that was conditional on mmutype, and netbsd-current
has it conditional on a cpu.quirk, at the moment this is unconditional, the
performance hit is arguable...

Fundamnetal type has not changed (was int on alpha and long on others).

of the other special virtual addresses and also provide visibility

really doesn't make a lot of sense if you're actually going to use these
as some recent changes to netinet/* want to do. (x) or (u_int*_t) (x)
would be the ticket, and since the rest of the ports settle for (x)...
Note that powerpc has this same problem and needs to be fixed!

named ioctls, but we have always preserved the names of the original code's
authors, unlike NetBSD...)
