compile the isp driver.

49a2507bd1 Migrate the thread stack management functions from the machine-dependent
to the machine-independent parts of the VM.  At the same time, this
introduces vm object locking for the non-i386 platforms.

Two details:

1. KSTACK_GUARD has been removed in favor of KSTACK_GUARD_PAGES.  The
different machine-dependent implementations used various combinations
of KSTACK_GUARD and KSTACK_GUARD_PAGES.  To disable guard page, set
KSTACK_GUARD_PAGES to 0.

2. Remove the (unnecessary) clearing of PG_ZERO in vm_thread_new.  In
5.x, (but not 4.x,) PG_ZERO can only be set if VM_ALLOC_ZERO is passed
to vm_page_alloc() or vm_page_grab().

66422f5b7a Initiate deorbit burn for the i386-only a.out related support. Moves are
under way to move the remnants of the a.out toolchain to ports.  As the
comment in src/Makefile said, this stuff is deprecated and one should not
expect this to remain beyond 4.0-REL.  It has already lasted WAY beyond
that.

Notable exceptions:
gcc - I have not touched the a.out generation stuff there.
ldd/ldconfig - still have some code to interface with a.out rtld.
old as/ld/etc - I have not removed these yet, pending their move to ports.
some includes - necessary for ldd/ldconfig for now.

Tested on: i386 (extensively), alpha

5244eac968 Complete rework of the PowerPC pmap and a number of other bits in the early
boot sequence.

The new pmap.c is based on NetBSD's newer pmap.c (for the mpc6xx processors)
which is 70% faster than the older code that the original pmap.c was based
on.  It has also been based on the framework established by jake's initial
sparc64 pmap.c.

There is no change to how far the kernel gets (it makes it to the mountroot
prompt in psim) but the new pmap code is a lot cleaner.

Obtained from:	NetBSD (pmap code)

recent changes (KSE and VM requiring physmem to be setup).

d27f1d4c12 This commit (along with one pending in sys/dev/ofw and one in sys/conf) give
us our first minimal glimpse of PowerPC support.

With this code we can get to the "mountroot>" prompt on my Apple iMac.  We
can't get any further due to lack of clock and interrupt handling, among other
things.  This does however mean that pmap and VM are initialising.

We're fairly dependant on OpenFirmware at this point, but I hope to add
support for other classes of firmware at a later stage.
