Reserve system call numbers for the MAC framework. This will prevent
people working on the MAC tree from getting toasted whenever system call
numbers are allocated in the main tree (for example, for KSE :-).
Calls allocated: __mac_{get,set}_proc, __mac_{get,set}_{fd,file}().

properly (e.g, grouping of variables and the SYSCTL macro calls for them, where
the documentation has been added.)

are probably talking about some disk-device which wente away, so
return ENXIO instead of panicing.

Add a new variable mp_maxid. This is used so that per cpu datastructures may
be allocated as arrays indexed by the cpu id. Previously the only reliable
way to know the max cpu id was through MAXCPU. mp_ncpus isn't useful here
because cpu ids may be sparsely mapped, although x86 and alpha do not do this.
Also, call cpu_mp_probe much earlier so the max cpu id is known before the VM
starts up. This is intended to help support per cpu queues for the new
allocator, but may be useful elsewhere.

Add generalized power profile code.
This makes other power-management system (APM for now) to be able to
generate power profile change events (ie. AC-line status changes), and
other kernel components, not only the ACPI components, can be notified

- move subroutines in acpi_powerprofile.c (removed) to kern/subr_power.c
- call power_profile_set_state() also from APM driver when AC-line
status changes
- add call-back function for Crusoe LongRun controlling on power

Allocate tlb contexts on the fly in cpu_switch, instead of statically 1 to 1
with pmaps. When the context numbers wrap around we flush all user mappings
from the tlb. This makes use of the array indexed by cpuid to allow a pmap
to have a different context number on a different cpu. If the context numbers
are then divided evenly among cpus such that none are shared, we can avoid
sending tlb shootdown ipis in an smp system for non-shared pmaps. This also
removes a limit of 8192 processes (pmaps) that could be active at any given
time due to running out of tlb contexts.

Fix obscure problems with vfork where part of the parent's stack could be
clobbered by the child. This is more complicated than usual because the
window that could get clobbered is pushed in kernel mode, so a lot of
registers would have to be saved in other registers in userland and we
don't have enough. What we do have is space in the pcb to temporarily
store user windows that were spilled in kernel mode, but could not be
immediately stored to the user stack. So we copy in the parent's topmost
window and save it in the pcb, and arrange for it to be copied back out
when the child is done frobbing the stack.

Fix bug in mb_alloc that made systems configured with
PAGE_SIZE / MCLBYTES == 1 crash. Fix them by changing the

Major update of the ATA RAID code, part 3:
Add code to properly detach/attach disks that are part of a RAID.
Mark a disk that is attached on an ATA channel belonging to a
RAID as a spare disk that can be used for rebuilding failed RAID1's.
Add support for rebuilding failed RAID1's.
Several fixes to the detach/attach code.
For replacing a disk in a failed RAID1 do the following:
Find the controller channel# of the failed disk.
Exec 'atacontrol detach <channel#>' to free the disk from the system.
Replace the failed disk with a new one of at least the same size.
If your have your disks in drawers/enclosures this can be done with
the system still running.
Exec 'atacontrol attach <channel#>' to add the disk to the system and
mark it as a valid spare for rebuild.
Exec 'atacontrol rebuild <array#>'
The system will rebuild the array on the fly, the array can still
be used during this, although with slower performance.
- Sort some entries.
- Don't remove MATH_EMULATE and MSDOS from a 'SMALL' floppy.
- Use the pattern '<tab><device name><tab>' instead of '<device name>' to
avoid an unexpected matching.
