non-cached. XXX clean this up by looking at the "non-cacheable" bit of
the full physical address.
avoid having 'nbuf' change between calls to `mdallocsys()' by setting it
in mdallocsys() like the MI allocsys() does. XXX fix this too!
fix some printf lossage.
update for probeget() changes -- though bus_space_probe() appears to be
unused on the sparc64.
looking up a kernel address, check to see if the address is on this
"interrupt-safe" list. If so, return failure immediately. This prevents
a locking screw if a page fault is taken on an interrupt-safe map in or
out of interrupt context.
device declaration, we don't want it). pull in psycho, pci,
ata and pciide code. clock, eeprom and power attach at sbus
*and* ebus now (clock as `eeprom' works). add `lpt at ebus',
wd major number, and other misc. commented devices.

field.
According to disklabel.h, its LFS semantics are "segment shift" (log2(segment
size)), but in the code it is used nowhere, and there are even plans to
allow non-poweroftwo segment sizes, so it won't ever work.
While at this, simplify the disktab-like output routine... here, currently,
BSDFFS, BSDLFS, EX2FS and ADOS do the same, so don't duplicate the code.
before the elimination of typematic events.
This fixes the case where the "extended" prefix was not ignored and
affected the next keystroke. (seen with the AltGr key)
(`SUNW,sabre') for now, and it doesn't really quite work there yet anyway.
the bus space/dma code is cloned from the sbus driver. the IOMMU code also
is cloned from the sbus code, but separated out into iommu.c so that we can
share it with the sbus driver. hopefully, much of the bus space/dma code
can also be re-shared with the sbus driver and the ebus driver but for now
these copies will do.
support for the real UltraSPARC PCI (`SUNW,psycho') is unwritten, though
most of this code is shared with it.
we can probe PCI config space and try to configue devices, but interrupts
don't work yet...
the bus space/dma code is cloned from the PCI code to do the same thing
which itself was cloned from the sbus bus space/dma code. the bus dma
code is non-functional at this point.
component failures! Also: remember to configure the disk queues for
the spares -- failure to do that is Bad(tm).
Huge Thanks to Martin Laubach for helping track this down.
