9539d5b4f6 Remove PAGE_SIZE_4K, PAGE_SIZE_8K and PAGE_SIZE_16K and replace them
with LOG2_PAGE_SIZE. A single option is better to LINT than multiple
mutual exclusive ones.

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().

367165975d Kill MID_MACHINE, its a.out specific, the only platform that supports
it is i386. All of the other platforms should remove it too.

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

23c12a63cf o Remove namespace pollution from param.h:
-  Don't include ia64_cpu.h and cpu.h
   -  Guard definitions by  _NO_NAMESPACE_POLLUTION
   -  Move definition of KERNBASE to vmparam.h

o  Move definitions of IA64_RR_{BASE|MASK} to vmparam.h
o  Move definitions of IA64_PHYS_TO_RR{6|7} to vmparam.h

o  While here, remove some left-over Alpha references.

ce5c49f1aa Merge fixes for dbtob() and btodb() from alpha/include/param.h. This stops
ffs_snapshot() from using negative numbers for byte offsets in large file
systems.

b40ce4165d KSE Milestone 2
Note ALL MODULES MUST BE RECOMPILED
make the kernel aware that there are smaller units of scheduling than the
process. (but only allow one thread per process at this time).
This is functionally equivalent to teh previousl -current except
that there is a thread associated with each process.

Sorry john! (your next MFC will be a doosie!)

5e115a7e04 - Define and use MAXCPU like the alpha and i386 instead of NCPUS.
- Sort the sys/mutex.h include in mp_machdep.c into a closer to correct
  location.

c794ceb56a Implement write combining for crashdumps. This is useful when
write caching is disabled on both SCSI and IDE disks where large
memory dumps could take up to an hour to complete.

Taking an i386 scsi based system with 512MB of ram and timing (in
seconds) how long it took to complete a dump, the following results
were obtained:

	WCE           TIME		WCE           TIME

ec222a71d9 Cleanup comment in machine/param.h regarding mbuf-related sizes, and get rid
of MCLOFSET, which does not appear to be used anywhere anymore, and if it is,
it probably shouldn't be.

1ebcad5720 This is the first snapshot of the FreeBSD/ia64 kernel. This kernel will
not work on any real hardware (or fully work on any simulator). Much more
needs to happen before this is actually functional but its nice to see
the FreeBSD copyright message appear in the ia64 simulator.
