 1.23  20-Feb-2011  matt Merge forward matt-nb5-mips64
Adapt to new interrupt/spl framework
(XXX don't know how to deal with use of spllower in sleep/pause code so
hpcmips kernel will fail to compile).
 1.22  04-Jan-2008  ad branches: 1.22.28; 1.22.32; 1.22.38; 1.22.40;
Don't pull in unrelated gunk.
 1.21  03-Dec-2007  ad branches: 1.21.6;
Interrupt handling changes, in discussion since February:

- Reduce available SPL levels for hardware devices to none, vm, sched, high.
- Acquire kernel_lock only for interrupts at IPL_VM.
- Implement threaded soft interrupts.
 1.20  17-Oct-2007  garbled branches: 1.20.2;
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.
 1.19  17-Jun-2007  tsutsui branches: 1.19.8; 1.19.10;
Move declaretions of _spl*() and _{clr,set}softintr() functions
(which are in mips/locore.S) into <mips/locore.h>
from various MD files.
 1.18  16-Feb-2007  ad branches: 1.18.6; 1.18.8; 1.18.14;
Remove spllowersoftclock() and CLKF_BASEPRI(), and always dispatch callouts
via a soft interrupt. In the near future, softclock will be run from process
context.
 1.17  21-Dec-2006  yamt merge yamt-splraiseipl branch.

- finish implementing splraiseipl (and makeiplcookie).
http://mail-index.NetBSD.org/tech-kern/2006/07/01/0000.html
- complete workqueue(9) and fix its ipl problem, which is reported
to cause audio skipping.
- fix netbt (at least compilation problems) for some ports.
- fix PR/33218.
 1.16  15-May-2002  uch branches: 1.16.26; 1.16.56; 1.16.58;
obsolete intrcnt[].
 1.15  23-Sep-2001  uch branches: 1.15.4;
improve interrupt response.
 1.14  16-Sep-2001  uch rearrange struct platform@sysconf.h suitable for hpcmips.
overhaul hpcmips/hpcmips/. no actual changes.
 1.13  15-Sep-2001  uch switch from splvec to ipl_sr_bits.
 1.12  15-Sep-2001  uch ANSIfy.
 1.11  13-Jun-2001  enami branches: 1.11.2; 1.11.4;
Generic softintr for hpcmips.
 1.10  13-Apr-2001  thorpej Remove the use of splimp() from the NetBSD kernel. splnet()
and only splnet() is allowed for the protection of data structures
used by network devices.
 1.9  12-Apr-2001  thorpej splvec.splimp -> splvec.splvm
 1.8  14-Jan-2001  thorpej branches: 1.8.2;
Make sure everybody has an splvm() and equate it with splimp() (splimp()
is the historical name for this interrupt level, and the historical name
is going to go away in the near future).
 1.7  22-Aug-2000  thorpej Add spllock(). See spl(9) for details.
 1.6  21-Aug-2000  thorpej Make sure we provide splsched() as described in spl(9).
 1.5  11-Apr-2000  uch sync with new mips trap.c
 1.4  03-Apr-2000  soda splsoftnet() should block softclock() too.
 1.3  03-Apr-2000  sato mips_hardware_intr is defined in <mips/intr.h>
 1.2  21-Nov-1999  uch TX3912/3922 support
 1.1  16-Sep-1999  takemura branches: 1.1.1;
Initial revision
 1.1.1.1  16-Sep-1999  takemura branches: 1.1.1.1.2; 1.1.1.1.8;

 1.1.1.1.8.1  27-Dec-1999  wrstuden Pull up to last week's -current.

 1.1.1.1.2.2  18-Jan-2001  bouyer Sync with head (for UBC+NFS fixes, mostly).
 1.1.1.1.2.1  20-Nov-2000  bouyer Update thorpej_scsipi to -current as of a month ago
A i386 GENERIC kernel compiles without the siop, ahc and bha drivers
(will be updated later). i386 IDE/ATAPI and ncr work, as well as
sparc/esp_sbus. alpha should work as well (untested yet).
siop, ahc and bha will be updated once I've updated the branch to current
-current, as well as machine-dependant code.
