26f56b9cab Only use __builtin_va_alist_t if using GCC 2.96 or later. Fixes 
pkg/10080, from Matthias Scheler.

8fedbd8497 Add i386-specific part of MicroChannel Architecture bus support, as 
found in some older IBM PS/2 machines.

This code is based upon work by Scott D. Telford, with some minor bits
in arch/i386/mca/mca_machdep.c taken from FreeBSD.

XXX this is still very experimental and development version; use at your
XXX own risk

855b79db92 Let each platform typedef the new __cpu_simple_lock_t, which should 
be the most efficient type used for the atomic operations in the
simplelock structure, and should also be __volatile.

f51470a514 Require that each each MACHINE/MACHINE_ARCH supply a lock.h. This file 
contains the values __SIMPLELOCK_LOCKED and __SIMPLELOCK_UNLOCKED, which
replace the old SIMPLELOCK_LOCKED and SIMPLELOCK_UNLOCKED.  These files
are also required to supply inline functions __cpu_simple_lock(),
__cpu_simple_lock_try(), and __cpu_simple_unlock() if locking is to be
supported on that platform (i.e. if MULTIPROCESSOR is defined in the
_KERNEL case).  Change these functions to take an int * (&alp->lock_data)
rather than the struct simplelock * itself.

These changes make it possible for userland to use the locking primitives
by including <machine/lock.h>.

8c5710a861 - Declare biosbasemem and biosextmem in <machine/cpu.h>, don't extern 
them everywhere they're used.
- Avoid integer overflow when converting bios{base,ext}mem (in units of
  kilobytes) to bytes.

dc80cc068b Move KERNBASE to 0xc0000000, giving the kernel a more-or-less full 1G 
of virtual address space, leaving userland with 3G, and update comments
to match the new reality.

We knew we were going to have to bite this bullet eventually, and there
are a couple of outstanding PRs related to this issue (9389 and 9313).
Complete solution to those PRs is going to involve some sort of run-time
decision on how large kmem_map should be, as well as changing some data
structure allocation strategies in UVM.  However, this change will at
least allow the PR submitter to simply throw resources at the problem.

b678bca85b Allow loading of kernels larger than (16-1)M. 
XXX This is a stopgap fix which can be pulled up to 1.4.x. It only replaces
the arbitrary 16M boundary by an arbitrary 128M boundary. A clean solution
would need changes to the mi loadfile.c parts.
