46289e1fef Phase out the use of a string as first "attach args" member to control
which bustype should be attached with a specific call to config_found()
(from a "mainbus" or a bus bridge).
Do it for isa/eisa/mca and pci/agp for now. These buses all attach to
an mi interface attribute "isabus", "eisabus" etc., and the autoconf
framework now allows to specify an interface attribute on config_found()
and config_search(), which limits the search of matching config data
to these which attach to that specific attribute.
So we basically have to call config_found_ia(..., "foobus", ...) where
such a bus is attached.
As a consequence, where a "mainbus" or alike also attaches other
devices (eg CPUs) which do not attach to a specific attribute yet,
we need at least pass an attribute name (different from "foobus") so
that the foo bus is not found at these places. This made some minor
changes necessary which are not obviously related to the mentioned buses.

e4726fc65d Add pmap counters for reclaimed pvos and for the times a pvo could not be
obtained.
Switch to EVCNT_ATTACH_STATIC*
In DEBUG/DIAGNOSTIC, decrement/increment pmap_pvo_enter_depth around pool
calls since they could possibly cause a recursion back into pmap_pvo_enter.

80c0e76172 implement pmap_pvo_reclaim(), which steals an existing non-wired pvo entry
for reuse, and use this in pmap_pvo_enter() when we can't allocate a new one.

9ff70d0082 Assembly versions of commpage functions for Powerpc, by Peter Grehan.
bigcopy is still missing

26200ee754 In MacOS X.3, the kernel maps tw opages of memory in every user process.
This areas is called the comm pages. It is used to provide fast access to
several data and functions.

The comm pages are mapped starting at 0xffff800 (address chosed so that
absolute branch can be used, so it can be accessed even when dynamic linking
is not ready). NetBSD has the user stack here, so we need to provide a
Darwin-specific stack setup routine which sets the top of the stack at
0xbfff0000.

This implementation is not complete but it does enough to get MacOS X.3
starting again (static binaries run, dynamic binaries still have an issue).
in the comm pages functions, we only implement bcopy, pthread_self and
memcpy.

TODO:
- clean up the powerpc specific code from MD parts
- for now we map only one page to avoid a crash, we want two pages.
- write all the comm functions.

0fea7f39a2 On OEA, turn PSL_USER* into runtime values appropriate for the CPU model
we're executing on; besides dealing with the bits not implemented in the
601's MSR it also removes the silent failure behaviour when passing
PSL_VEC set on a CPU not implementing it.

Also, fix those masks for the 4xx again.

8a98994beb Get rid of the silly CPU601 hooks and move BAT register restoration and
obliteration to RESTORE_{KERN,USER}_SRS, respectively; have oea_init()
patch these sequences to be skipped on non-MPC601s.  The code sequence
matching heuristic isn't as pretty as the one for VRSAVE and MQ but works
well enough with the current structure of the trap code, and can be easily
updated when necessary.
