allow pcu_save() and pcu_discard() to be called on other threads,
ptrace needs to use it that way.

-extend the pcu(9) API by a function which saves all context on the
current CPU, and use it if a CPU is taken offline
-add a bool argument to pcu_discard which tells whether the internal
"LWP has used the coprocessor" flag should be set or reset. The flag
is reported by pcu_used_p(). If set, future accesses should use the
state stored in the PCB. If reset, it should be reset to default.
The former case is useful for setmcontext().
With that, it should not be necessary anymore to manage the "FPU used"
state by an additional MD variable.

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.

matt | branches: 1.13.12;
Add a SAVE/DISCARD flag to save_{fpu,vec}_lwp. Use it appropriately.
Nuke struct fpu and use struct fpreg instead (except for the names, they
were identical). On MP machines, this will avoid an unneeded IPI to save
the register contents that are about to discarded.

Add a port to IBM's PPC405GP Reference Board (the "walnut")
by Eduardo Horvath and Simon Burge of Wasabi Systems.
IBM 4xx series CPU features:
- New pmap and revised trap handler.
- Support on-chip timers, PCI controller, UARTs
- Framework for on-chip ethernet and watchdog timer.
General PowerPC features:
- Add in-kernel PPC floating point emulation
- New in{,4}_cksum that is between 1.5 and 5 times faster than the
old version depending on CPU type.
General changes:
- Kernel support for generic dbsym-style symbols.

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.

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
code to restore CR4 before jumping back into kernel space as the large
page option might cover that.

garbled | Move a bunch of the macppc SMP code out of macppc, and down into the
generic OEA code. Add a set of md callbacks into these shared routines,
that any oeappc SMP machine needs to provide. This allows for generally
shared SMP startup code, but still allows for machine-specific
differences in the setup and kicking of the new CPU.
Convert macppc to this new layout. Tested by Macallan.
Add an initial attempt at SMP to prep. Tested on UP machine only,
untested on SMP yet.

matt | Add SPE (signal processing engine) support for mpc85xx/booke. Think of it
as AltiVec-lite (really lite). Genercize AltiVec support so that it could
the same interface could support SPE as well. Rework the FPU support along
the same lines. Move the __asm() to their own XXX_subr.S (altivec, fpu, spe).
