struct scsipi_adapter; they were not used.
Add a scsipi_ioctl entry point to struct scsipi_adapter. This will be
used to issue ioctl commands to the host adapters.
Inspired by PR #6090, from Matt Jacob.
which require special handling, e.g. sigreturn on m68k.
This differs from the old sigreturn trap in that we require the syscall
number to be in register d0, just like the regular syscall entry point.
This will allow sigreturn to be versioned in the future without the need
to allocate another trap vector.
u-area in machine-dependent code. Instead, call exit2() to schedule
the reaper to free them for us, once it is safe to do so (i.e. we are
no longer running on the dead proc's vmspace and stack).
with other PowerBook hardware. They seem to be most closely related
to the PowerBook 500-series, but have an internal IDE disk instead.
NOTE: only external SCSI disks have a chance of working, at this
point. Nothing has officially changed with regard to IDE support
(yet).

- Interrupts 3-6 use this immediately. Interrupt 7 is a special case,
and the VIA interrupts (1 and 2) will be addressed when that code is
rototilled.
- Modify the zs front end to register with the appropriate interrupt
controller: through the PSC on the AV Quadras, and direct to
interrupt 4 on the rest. Arrange to have the appropriate zsc_softc
supplied to us at interrupt time.
- Modify the direct ADB driver (and its PowerManager cousin) to call
intr_dispatch(), rather than zshard(). XXX This is a kludge, but at
least limits the brokenness to the ADB drivers, now.
As a side effect, this should fix PR 5590. Thanks to Bill Studenmund for
correctly determining the cause of the problem reported there.

resolves a great many issues, including Performa 58x interrupt handling
and offset displays on some models.
Programs that depend on the old (pre-NetBSD 1.1) grf interface may break.
That's actually a separate issue uncovered by this code, not caused by it.
