Retire ipkdb entirely. The option was removed from the config files
yesterday.

Don't include *pmap.h in assembly files. Get the needed definitions
from "assym.h".

Make struct cpu_info the same size if building MODULAR
kernels or compiling a module.

Make a common genassym.cf (powerpc/genassym.cf) and then
only put specific stuff in foo/genassym.cf

Add things needed for __HAVE_FAST_SOFTINTRS

Remove <machine/atomic.h>; use <sys/atomic.h> instead.
Add <powerpc/cpuset.h> (for mpc85xx pmap).
Add some initial MP code for mpc85xx
Rework ipi code to be common across all ppcs
Change PPC to keep curlwp in %r13 while in the kernel.
Move astpending from cpu_info to mdlwp
Improve cpu_need_resched to be more MP friendly.

branches: 1.18.4;
Add support for BookE Freescale MPC85xx (e500 core) processors.
Add fast softint support for PowerPC (though only booke uses it).
Redo FPU/VEC support and add e500 SPE support.
Rework trap/intrs to use a common trapframe format.
Support SOFTFLOAT (no hardfloat or fpu emulation) for BookE.

branches: 1.17.2;
fix copy{in,out}{,str}() to return the error returned by uvm_fault().
fixes PR 41813.

branches: 1.16.2; 1.16.4;
Rename L_ADDR to L_PCB and amend some comments accordingly.

branches: 1.15.4; 1.15.26;
Add MTX_* and RW_* definitions

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.

branches: 1.13.10;
Fix for yamt-idlelwp merge.

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.

branches: 1.11.26; 1.11.30; 1.11.32; 1.11.38;
merge ktrace-lwp.

branches: 1.10.8;
Split the hw-dependent powermanglement into its own function and make
Idle call that. Add a ci_idlespin function pointer to cpu_info.
Update INIT_CPUINFO to initialize it to a naked 'blr' instruction.
In oea/cpu_subr.c, add cpu_idlespin and make ci_idlespin point to it.

branches: 1.9.8;
Need offset of ci_curpm in struct cpu_info on 4xx as well.

Move SFRAMELEN to frame.h and use it in vm_machdep.c. In setfunc, setup
callframe linkages correctly. Restore use of ldptr to locore_subr.S
[pthreads and gdb no longer crash/hang the system]

Cleanup/rework cpu_switch*, switch_exit, Idle routine. Remove pcb_psl
since it was write-only. When setting up a process, make sure the fake
callframes are properly linked together.

Only lower SPL when in Idle loop. Raise spl to previous level (which would
be IPL_SCHED) when exiting Idle loop. Never lower SPL anyplace else.

Nuke ci_curpm and curpm. Nuke pcb_pmreal. Those were use for spill stacks
and those no longer exist. for few uses that need CURPM, use CURPCB/PCB_PM

catch up with changes elsewhere.

Add SFRAME_USER_SR (even though the 4XX doesn't have one).

Add each register in trapframe, switchframe, and faultbuf.

SZ_BOARD_CFG_DATA is not used anywhere, remove it.

branches: 1.1.2;
Re-arrange things in evbppc & powerpc to support OEA-based eval boards
in evbppc. OEA-based board(s) to be added later.
