 1.15  22-May-2017  ragge Update copyright notice for Ludd (remove clause 3 & 4).
 1.14  25-May-2012  matt branches: 1.14.2; 1.14.16;
Implement __HAVE_RAS. Unlike most implementation, this is done in userret
instead of cpu_switchto since we already accessing the proc structure so
the additional overhead of check p_raslist is minimal.
 1.13  03-Jul-2011  matt branches: 1.13.2; 1.13.6;
Cleanup trapframe handling. Instead of keeping a trapframe pointer in the
pcb, put in the mdlwp instead. We had a dummy field so it didn't grow in
size. This also follows the practice that mips and powerpc follow that a
pointer to the user trapframe is in l->l_md.md_utf. Make trapframe members
start with tf_
 1.12  27-Feb-2010  snj Spell "exception" properly.
 1.11  22-Oct-2008  hans branches: 1.11.14;
fix userret() and resurrect cpu_setfunc() to make vax build again. ok by matt.
 1.10  15-Oct-2008  wrstuden Merge wrstuden-revivesa into HEAD.
 1.9  05-Nov-2007  ad branches: 1.9.16; 1.9.20; 1.9.22; 1.9.26;
Don't set l_usrpri / spc_curpriority here. mi_userret() does it.
 1.8  17-Oct-2007  garbled 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.
 1.7  01-Oct-2007  ad branches: 1.7.2;
ci_need_resched -> ci_want_resched
 1.6  17-May-2007  yamt branches: 1.6.8; 1.6.10; 1.6.12;
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.
(cf. gmcgarry_ctxsw)
2. implement idle lwp.
3. clean up related MD/MI interfaces.
4. make scheduler(s) modular.
 1.5  19-Feb-2007  matt branches: 1.5.4; 1.5.6; 1.5.12;
L_USERRET -> LW_USERRET
 1.4  17-Feb-2007  matt branches: 1.4.2;

- move sched_changepri back to kern_synch.c as it doesn't know PPQ anymore.
