for both structs, the new members are 'bps' and 'msb', which
describe the number of bytes per sample and data alignment in the
sample, respectively. drivers must properly set these fields in
the 'query_encoding', 'set_parameters' and 'get_default_params'
hardware interface methods.

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.

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.

result: kernels built without 'make depend'-provided information
(ie. the .depend file) are more likely to have their *.[Ss] file
compilations track changes to *.h files.
The "*.o: assym.h" dependencies listed are gotten from reading the
.depend output --- from the biggest kernel possible (ie. GENERIC.MP).
When an architecture changes in a substantial way (new .[sS] files),
the list should be updated in the prettiest way possible.
This is not encouraging people to skip 'make depend'; other issues are
not resolved and may be solved later with a change guenther is working
on. You can still screwed really easily, so continue running make
depend as config tells you.

gets rid of #include <sys/dkio.h> in sys/ioctl.h and adds #include
<sys/dkio.h> to the places that actually want and use the disk

this became an issue when krw@'s X build failed when he was testing
a change to dkio.h.

Instead of previous implementation, we won't use physical cpuid to fetch curcpu().
This requires to implement IP27/35 SMP.
Implemented getcurcpu() and setcurcpu() for it, smp_malloc() renamed alloc_contiguous_pages() because now it only allocate by page.

two directories. in reality, because of how we place files, it has four:
.../arch/A, .../arch/A/A, .../arch/M, and .../arch/M/M
formalize this A/A and M/M scheme directly in the Makefiles, which makes
them a lot more similar

two distinct sets of routines: one for the ARCBios-compatible path used on
non-KL systems (such as O2 and Octane), and one for the KL system using
dksc() paths.
When trying to match a dksc() path, walk the KL configuration of the whole
system until the dksc controller is found; since the controller numbers are
not assigned sequentially and contiguously, the old code would not work on
complex systems (such as when booting from controller #6 when #3 to #5 are
unaffected).

and routines to turn a KL console and a KL component structs, respectively,
into struct sgi_device_location for further device identification.
XXX Due to the way PCI devices are numbered on PIC buses, this code is tainted
XXX by knowledge about PIC widgets, to compensate. I have considered changing
XXX xbridge(4) to have our PCI device numbering match KL on PIC-connected
XXX devices, but I expect this to be even uglier. This is not settled yet.
