martin | PR 58960: fix misunderstanding in semantic and provide both the original
id string as well as _NETBSD_REVISIONID.
Do not rely on string concatenation in the inline assembler, use .ascii
and .asciz for individual string parts instead.

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:

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.

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.

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:
