- Only do an outb() to the PIC to clear a bit in imen if the bit is set.
- Add a NUM_ISA_IRQS macro to replace uglier
'sizeof(array) / sizeof(member)' expressions along with a CTASSERT() to
ensure that the macro is correct.

If this breaks your laptop, please let me know how it does it :-)

there are a lot of other dependencies that preclude the kernel from
working). Instead, have a more generic note that isa should not be
removed. This should be less confusing for users.
different BIOSs use the same exact settings to mean two very different and
incompatible things for the SCI. Thus, if the SCI is remapped to a PCI
interrupt, we now trust the trigger/polarity that the MADT provides by
default. However, the SCI can be forced to level/lo as 1.10 did by setting
the tunable "hw.acpi.force_sci_lo" to a non-zero value from the loader.
Thus, if rev 1.10 caused an interrupt storm, it should nwo fix your
machine. If rev 1.10 fixed an interrupt storm on your machine, you
probably need to set the aforementioned tunable in /boot/loader.conf to
prevent the interrupt storm.
The more general problem of getting the SCI's trigger/polarity programmed
"correctly" (for some value of correctly meaning several workarounds for
broken BIOSs and inconsistent "implementations" of the ACPI standard) is
going to require more work, but this band-aid should improve the current
situation somewhat.

change the video output but use a separate device with a DSSX method
and a HID of "TOS6201" instead. We use a pseudo-driver to get the handle
for this object and pass it to the acpi_toshiba driver.
This is untested but seems to match the Linux Toshiba driver.
move its declaration to the machine-dependent header file on those
machines that use it. In principle, only i386 should have it.
Alpha and AMD64 should use their direct virtual-to-physical mapping.

without the (defunct) isa compatibility shims. The new-bus-specific
parts are very similar to the ones for the pci probe and attach.
This was held up too long waiting for a repo copy to src/sys/dev/cy,
so I decided to fix the files in their old place. This gives easier
to read and merge diffs anyway.
The "count" line in src/sys/conf/files won't be changed until after
the repo copy, so old kernel configs that specify a count need not be
(and must not be) changed until then. The count is just ignored in
the driver. One unfinished detail is dynamic allocation of arrays
with <count> and (<count> * 32) entries, and iteration over the arrays.
This is now kludged with a fixed count of 10 (up to 10 cards with up
to 32 ports each).

This fixes breakage of the initialization of the lock in the pci case
in rev.1.135 (between the releases of 5.1 and 5.2). The lock is only
used in the SMP case, so this bug was not always fatal.

more correct or not (technically speaking).
