doesn't seem to honour the a.out entry point, we need to include
a little assmbler file which jumps to where we want to be in C.

if called by pipeselwakeup(), it is held. Whereas, if called by kqueue_scan(),
it is not.)

There is still some locations where the PROC lock should be held
in order to prevent inconsistent views from outside (like the
proc->p_fd fix for kern/vfs_syscalls.c:checkdirs()) that can be
fixed later.

This completes the ATA RAID support, since all functions to manipulate
the RAID are accessible from FreeBSD, the BIOS on the ATA RAID cards
are only nessesary for booting.
I decided to allow for creation of ATA RAID's on any ATA controller, but
please keep in mind the restrictions on that. Due to the BIOS not
knowing what to do you can only boot from a RAID1 or the first disk
in a SPAN, if its not located on a "real" ATA RAID controller like
the Promise or Highpoint controllers.

with this flag. Remove the dup_list and dup_ok code from subr_witness. Now
we just check for the flag instead of doing string compares.
Also, switch the process lock, process group lock, and uma per cpu locks over
to this interface. The original mechanism did not work well for uma because
per cpu lock names are unique to each zone.

disablement assumptions in kern_fork.c by adding another API call,
cpu_critical_fork_exit(). Cleanup the td_savecrit field by moving it
from MI to MD. Temporarily move cpu_critical*() from <arch>/include/cpufunc.h
to <arch>/<arch>/critical.c (stage-2 will clean this up).
Implement interrupt deferral for i386 that allows interrupts to remain
enabled inside critical sections. This also fixes an IPI interlock bug,
and requires uses of icu_lock to be enclosed in a true interrupt disablement.
This is the stage-1 commit. Stage-2 will occur after stage-1 has stabilized,
and will move cpu_critical*() into its own header file(s) + other things.
This commit may break non-i386 architectures in trivial ways. This should
be temporary.

new vfs_getopt()/vfs_copyopt() API. This is intended to be used
later, when there will be filesystems implementing the VFS_NMOUNT
operation. The mount(2) system call will disappear when all
filesystems will be converted to the new API. Documentation will
be committed in a while.

modules (ie. procfs.ko).
When the kernel loads dynamic filesystem module, it looks for any of the
VOP operations specified by the new filesystem that have not been registered
already by the currently known filesystems. If any of such operations exist,
vfs_add_vnops function calls vfs_opv_recalc function, which rebuilds vop_t
vectors for each filesystem and sets all global pointers like ufs_vnops_p,
devfs_specop_p, etc to the new values and then frees the old pointers. This
behavior is bad because there might be already active vnodes whose v_op fields
will be left pointing to the random garbage, leading to inevitable crash soon.

The conclusion is that this method really can tell the perfect from the
less than perfect ACPI counters.
It is in fact probably a bit more discriminative than that, but we
will rather condemn some otherwise perfect counters to the slightly
slower "-safe" version, than certify a counter as perfect which
will let us down later.
Many thanks to all the people who sent email reports!

Also, grab the uma_mtx while in the sysctl handler. This hadn't caused

- change the IOMMU support code so that it supports overcommittting the
available DVMA memory, while still allocating as lazily as possible.
This is achieved by limiting the preallocation, and deferring the
allocation to map load time when it fails. In the latter case, the
DVMA memory reserved for unloaded maps can be stolen to free up enough
memory for loading a map.
- allow NULL settings in the method tables, and search the parent tags
until an appropriate implementation is found. This allows to remove some
kluges in the old implementation.

Kluge the interrupt routing methods of the psycho and apb drivers so
that an intline of 0 can be handled for now; real routing is still not
possible (all intline registers are preinitialized instead); this will
require a sparc64-specific adaption of the driver for generic PCI-PCI
bridges with a custom routing method to work right.

- remove some useless code from the status change handler that was intended
to enable the the MII drivers for external phys; this is already done
during interface initialization, and the deleted code made some
assumptions about phy addresses that do not seem to hold true on newer
