assigned by RISCOS Ltd (and were assigned by Acorn) to be unique across all
manufacturers. This means that associating each one with a manufacturer (and
checking the manufacturer when attaching) is bogus. Thus, we don't do that
any more.
This should have the pleasant side-effect of getting APDL IDE interfaces
working, since they're just ICS ones with a different manufacturer ID.
into kernel_object where this was missing.
(important here because VM_MIN_KERNEL_ADDRESS != 0)
-add some diagnostics
-eliminate some differences to other Utah derived pmaps

This is a no-op on ports where VM_MIN_KERNEL_ADDRESS==0, ie all but
cesfic.

successfully emulates a few test program that use poll semaphores,
including the attach-to-file-descriptor-and-select feature.
There are a few issues:
1) at least one ioctl need to set retval. We handle this in irix_sys_ioctl()
by replacing the data argument by a pointer to a strucutre in the stackgap
that carries the real data and retval. The underlying ioctl methods can
therefore retreive both data and retval.
2) usemaclone is a cloning device: each time it is open, it creates a new
context, and ioctl operation on each open file descriptor will lead to
different behavior. This functionnality is available in NetBSD through the
devvp branch. This first implementation does not use devvp yet, but this
should be done later. Currently, we create a new vnode, and we provide our
own vnode operations. Some operation are applied to the cloned vnode, others
are applied to the original vnode. The v_data field is used to hold a
reference to the original vnode so that we can work on it.
3) at least the setattr vnode operation needs some customisation: IRIX
libc relies on the fact that fchmod on /dev/usema will return 0 in case
of failure.
intvid didn't find the frame buffer on his PB 170 in NetBSD 1.5. This is
because the PowerBook 140/145+145B/170 entries in intvid_info[] were
entered into the table directly from the corresponding hardware tech
notes. Unfortunately, the actual frame buffer is mapped at an offset
of 32 KB from the base of the region (at least when in 32-bit mode).
Since all 4 of these systems have identical video configurations, I'm
updating the rest to match.

two IIC ports, a timer, and a DRAM controller.
The driver supports PCI, interrupts and com ports.

This fixes the endless loop when reading directories on NFS, though
applications won't see all directory entries due to different problem.

boot loader image. Installboot can modify the default command in the
first-stage bootblocks, which will have no effect. Copy the default command
from the first-stage bootblock into the second-stage bootloader so modifying
the commandline with installboot actually works again.

The PUMA config is configured somewhat optimally for one of Allen's
Quadras but doesn't do anything special as compared to SMALLRAM.
