which contains the constraints for DMA/memory allocation for each
architecture, and dma_constraints which contains the range of addresses
that are dma accessable by the system.
This is based on ariane@'s physcontig diff, with lots of bugfixes and
additions the following additions by my self:
Introduce a new function pool_set_constraints() which sets the address
range for which we allocate pages for the pool from, this is now used
for the mbuf/mbuf cluster pools to keep them dma accessible.
The !direct archs no longer stuff pages into the kernel object in
uvm_km_getpage_pla but rather do a pmap_extract() in uvm_km_putpages.
Tested heavily by my self on i386, amd64 and sparc64. Some tests on
alpha and SGI.

of pci specific code and the rest of the driver. in hindsight, this was a
stupid thing to do in mpi since there will only ever be pci based mpi
controllers. the same goes for mpii, but unlink mpi it doesnt have the bus
and generic driver split at the file level, just in the code.
this merges the pci and generic mpii autoconf code so its just mpii
autoconf code. apologies for the files.pci change.
tested by me

walking the ruleset and up until state is fully set up) into pf_pdesc instead
of passing around those 4 seperately all the time, also shrinks the argument
count for a few functions that have/partialy had an insane count of arguments.
kinda preparational since we'll need them elsewhere too, soon

it defines. In some cases, this means pulling in uvm.h or pcb.h
instead, but most of the inclusions were just noise. Tested on
alpha, amd64, armish, hppa, i386, macpcc, sgi, sparc64, and vax,
mostly by krw and naddy.

must break out of the cases, not directly 'return' error codes. I
think the error case is currently impossible, but why leave an armed
bear trap lying about?

between an allocating process failing and waking up the pagedaemon
and the pagedaemon (since everything was dandy).
Rework the do ... while () logic searching for pages of a certain
memtype in a pmr into a while () loop where we check if we've found
enough pages and break out of the pmr and check the memtype inside
the loop. This prevents us from doing an early return without enough
pages for the caller even though more pages exist.

makes the ioctl and sensor paths more reliably now that they cant fail
due to a ccb allocation failure, and allows better sharing of resources
between multiple logical volumes and physical devices.

protects the ccb runqueues and the mailbox with a single mutex.
the biggest change as a consequence of this is a rewrite of the polled
command code. it now forces the polled command onto the chip ahead of the
pending runqueue, and simply runs the interrupt handler until the ccb
completes.

This is a leftover from a very old workaround for a very old and long gone

keyboard is connected but a framebuffer exists in the machine; the current
kernel console code will complain and switch to full serial, but later on
the framebuffer would incorrectly take over the console.
Correctly detect this situation and reset the `fbnode' variable. This is
an improvement of the fix which went in rev 1.54 of this file.
