EX_BOUNDZERO, to extent_alloc(). this fixes problems with it
(extent_alloc()) returning incorrect values, when the start of
the extent is not aligned as strongly as the requested area..
raw access to ide disks now works.

also includes a bunch of <vm/vm_page.h> include removals (due to redudancy
with <vm/vm.h>), and a scattering of other similar headers.
"off_t" and the return value is a "paddr_t" to allow mappings
at offsets past 2^31 bytes. Somewhat inspired by FreeBSD, which
only changed the offset to a "vm_offset_t".
Includes updates for the i386, pc532 and sh3 mmmmap from Jason Thorpe.
Unlike the other Sun machines, UltraSPARCs can have consoles run on different
chips than zs, so we need to support them. So, here we go:
Add a new PROM console driver with a major number and everything.
This is the default driver if nothing else attaches. It does not
use the keyboard driver since the PROM translates keystrokes itself.
(Unfortunately it also swallows L1-A).
Have the keyboard driver take over the console when it attaches on a
serial port. When a serial port detects a keyboard and attaches the
keyboard driver, it needs to provide a set of consdev vectors. They
keyboard driver will use those to send I/O to the keyboard and mouse.
just one copy of this.
- remove duplicate setting of sgsize in iommu_dvmamap_load().
- fix DIAGNOSTIC check in iommu_dvmamap_load_raw() to panic() in unexpected
conditions only (not normal ones), and also add an extra case.
it to determine the boot device: mvme68k, pc532, macppc, ofppc. Those
platforms should be changed to use device_register(). In the mean time,
those ports defined __BROKEN_DK_ESTABLISH.
- make some debugging messages in iommu_remove() saner and add some more.
- decrement 'len' in the no streaming buffer case, also.
- in iommu_dvmamem_map(), do not enter these mappings into the IOMMU,
only into the CPU (the former is done at _load time).
- make a panic that shouldn't happen a DIAGNOSTIC.
- merge IOMMU DVMA code from sbus/psycho into iommu.c. this code was
identical and a few minor inconsistencies had crept in. this way
keeps them all in sync.
- with this code gone from psycho, merge the psycho.c and psycho_bus.c
files. same with ebus/ebus_bus.c. delete the _bus.c files.
- add a _ds_boundary member to the dma segment structure, so that later
dma mappings can find this value.
- set _ds_boundary in machdep.c:_bus_dmamem_alloc().
- kill much dead code.
- make GENERIC64 include GENERIC and set the 3 optoins it needs. suggested
by hubert feyrer.
- add a comment that we maybe should use the `bpp' driver, not the lpt, on
the ebus because the `bpp' driver does DMA already.
- ebus_attach_args got a member renamed
