rin | Make ibm4xx kernels compiled by clang.
As clang cannot correctly assemble m[ft]pid:
- for asm sources, use m[ft]spr from/to SPR_PID
- for C sources, use M[FT]PID macros (see include/ibm4xx/spr.h)
This is ugly...
No binary changes for GCC-compiled kernels.

rin | Implement workaround for IBM405 Errata 77 (aka CPU_210), where
interrupted stwcx. may errantly write data to memory:
https://elinux.org/images/1/1d/Ppc405gp-errata.pdf
This is because stwcx. is split into two pieces in the pipeline.
We need to
(1) insert dcbt before every stwcx. instruction, as well as
(2) insert sync before every rfi/rfci instruction.
It is unclear which processors are affected, but according to Linux,
all 405-based cores up until 405GPR and 405EP are affected:
https://github.com/torvalds/linux/blob/master/arch/powerpc/platforms/40x/Kconfig#L140
For kernel, this workaround can be restricted to affected processors.
However, for kernel modules and userland, we have to enable it for all
32bit powerpc archs in order to share common binaries as before.
Proposed on port-powerpc:

PR port-powerpc/51367: kernel panic for powerpc/ibm4xx with "option DDB"
Stop using ddbstk/ipkdbstk to make nested traps possible, which avoids
kernel panics reported in the PR.
Suggested and approved by matt.

kiyohara | branches: 1.24.14; 1.24.18;
Fix KASSERT(l == curlwp)ed in mi_switch(). Don't use INTSTK of cpu_info in
INTR_PROLOG when user-mode. Interrupted user context switches to newlwp, if
sched tick. This context must save to USPACE.
When use our INTSTK?

cliff | - FRAME_SAVE_CALLEE() starts at r14 (not r13, which is curlwp) (from matt@)
- INTR_SAVE() must also save r13 (from matt@).
- fitint must pass clock frame, not trap frame
- fix comment in pitint and fitint to indicate passing clock frame, not intr frame

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.

Add fast softint support for PowerPC (though only booke uses it).

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.

that the user requested. For example:
0xd5c56f40: SC trap #240 by 0x15668c60: srr1=0xd032

matt | branches: 1.7.2;
Perform a rototill of the powerpc code. Mandate use of SPRG0 to store
a pointer to current cpu's cpu_info structure. Use cpu_info for
intstk,intr_depth,still_stk,idle_pcb,curpcb,curlwp,etal even on
non-MULTIPROCESSOR machines. Add common macros GET_CPUINFO and
INIT_CPUINFO to get and initialize the cpu_info struct on startup. Make
ibm4xx use the standard <powerpc/frame.h>. Use IFRAME_xx in ibm4xx
trap_subr.S instead of explicit magic offsets. Move INTSTK and SPILLSTK
to std.<platform>. Change faultbuf to a struct instead of an array.
On MPC6XX cpus, stop using the vector page for temporary space and use
reserved space in cpu_info.

Follow the merge of pmap.c on i386 and amd64 and move
pmap_init_tmp_pgtbl into arch/x86/x86/pmap.c. Modify the ACPI wakeup
