Update copyright notice for Ludd (remove clause 3 & 4).

use gcc builtin for memset() on vax too.

remove alias for _insque and _remque since they are no longer
used. leave the vax_insque function for no reason except that
it maps to an actual instruction.

sync the prototype of cpu_switchto with sys/cpu.h.

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.

merge yamt-idlelwp branch. asked by core@. some ports still needs work.

from doc/BRANCHES:

idle lwp, and some changes depending on it.

1. separate context switching and thread scheduling.

Use the ffs builtin in gcc4.1

s/volatile/__volatile

Kill caddr_t; there will be some MI fallout, but it will be fixed shortly.

Make GCC3/GCC4 happy with these asms.

Change "inline" back to "__inline" in .h files -- C99 is still too
new, and some apps compile things in C89 mode. C89 keywords stay.

As per core@.

__asm__ -> __asm
__const__ -> const
__inline__ -> inline
__volatile__ -> volatile

Remove leading __ from __(const|inline|signed|volatile) -- it is obsolete.

merge ktrace-lwp.

Preserve the const qualifier even if we cast the "from" argument in the
memcpy() and memmove() inline functions.

Tidy up the namespace: lint -> __lint__.

Remove ; after setrunqueue/remrunqueue macro.

Some of the vax-specific mem*() functions did not check for len > 65535,
and when MAXDSIZ were increased memcpy() length sometimes were larger
than 64k (like in amap_extend()) All functions now check

Some of the vax-specific mem*() functions did not check for len > 65535,
and when MAXDSIZ were increased memcpy() length sometimes were larger
than 64k (like in amap_extend()) All functions now checks the length.
This fixes PR#19968.

Disable the inline string functions and use the C versions instead.

Merge the nathanw_sa branch.

Update for cpu_switch() prototype changes. No functional change.

Add -ffreestanding and LIBC= to stand/boot/*/Makefile. Fix various
asm's to work with gcc-current.

Move .s files to .S files. (and .s.o rules in boot/Makefile.inc)
Put in register prefixes everywhere.

* Add __unused__ attribute to inline functions.
* Call __blkclr() and __blkset() as appropriate.

Add bbssi/bbcci (bit set/clear and branch interlocked) as inline functions.

Redefine the memset/memmove/bcopy/bzero/memset macros to use more agressive
constraints in their inline asm. Gcc generates much better code now.
