1df5f8294f Automatically issue a "continue" along with the "detach" command. This
fixes the problem of cleanly restarting a target after entering gdb mode.

If we do, we usually wrote backwareds into the proceeding partititon
which is usually the root partition.

92a306a2b6 Use the correct value when writing the Day Of Week byte in the CMOS.
The correct range is [1...7] with Sunday=1, but we have been writing
[0...6] with Sunday=0.

The Soekris computers flagged the zero, zapped the date, so if you
rebooted your soekris on a sunday, it would come up with a wrong
date.

Bruce has a more extensive rework of this code, but we will stick with
the minimalist fix for now.

b19d9defef Under certain circumstances, we were calling kmem_free() from
i386 cpu_thread_exit().  This resulted in a panic with WITNESS
since we need to hold Giant to call kmem_free(), and we weren't
helding it anymore in cpu_thread_exit().  We now do this from a
new MD function, cpu_thread_dtor(), called by thread_dtor().

ebff7660a3 *sigh*. It seems that in the ACPICA code, Intel defines its own APIC_IO
macro for use when parsing MADT tables, thus we always tried to set the
interrupt model to APIC.  This proved to be harmful on UP machines with
IO APIC's (or for UP kernels on SMP machines) since the wrong interrupt
routing information would be returned.

2be05b70c9 Add getcontext, setcontext, and swapcontext as system calls.
Previously these were libc functions but were requested to
be made into system calls for atomicity and to coalesce what
might be two entrances into the kernel (signal mask setting
and floating point trap) into one.

A few style nits and comments from bde are also included.

eea85e9bb6 Move pmap_collect() out of the machine-dependent code, rename it
to reflect its new location, and add page queue and flag locking.

Notes: (1) alpha, i386, and ia64 had identical implementations
of pmap_collect() in terms of machine-independent interfaces;
(2) sparc64 doesn't require it; (3) powerpc had it as a TODO.

   exported on sparc64.)

2be7d43928 Add a new loader tunable, hw.hasbrokenint12, to indicate that BIOS
has broken int 12H.
If hw.hasbrokenint12="1" in loader environment, kernel never use BIOS
INT 12 call to determine base memory size.
Otherwise, kernel use INT 12 in old behaviour.
This should fix kernel panic problem caused by 1.544 changes.

0fca57b8b8 Move the definitions of the hw.physmem, hw.usermem and hw.availpages
sysctls to MI code; this reduces code duplication and makes all of them
available on sparc64, and the latter two on powerpc.
The semantics by the i386 and pc98 hw.availpages is slightly changed:
previously, holes between ranges of available pages would be included,
while they are excluded now. The new behaviour should be more correct
and brings i386 in line with the other architectures.

Move physmem to vm/vm_init.c, where this variable is used in MI code.

  when the thread calling vm86 BIOS is preempted by interrupt thread,
