It seems I didn't count my 0's properly when adding the new masks into
icu_vector.s pushing SWI_AST_MASK off the end of the array and screwing
up the indexing for SWI_CLOCK_MASK.
Fix the bug icu_vector.s and also reformat the code in both icu_vector.s and
apic_vector.s so that it will be much harder to make the same mistake in
the future.

machine generates an NMI for each floating point error, just like an old XT.
Since it is ISA only, reading the EISA status port yields 0xff, which would
give a spurious EISA panic. The simplest thing to do is to ignore the 0xff.
operands that are set during seqeuncer program download instead of at
assembly time.
Remove the REJBYTE sram variable. The host driver can just as easly
read the accumulator to get this value.
This should fix the reported problems with cards that don't have devices
attached to them failing with a stream of "Somone reset bus X" messages.
Doug Ledford determined the cause of the problem, fixes by me.

- iso-2022 G0 designation support. This does almost nothing. Just for

total being the sum of both base and extended memory.

This probably fixes Soren's problem too, but he never mentioned
which CD driver he was using. 8-)

Add cpu_rootconf and cpu_dumpconf so that configuring these
two devices can be better controlled by the MI configuration

Add support for printing out whether cam interrupts are masked
during a panic.
plus the previous changes to use the zone allocator decrease the useage
of malloc by half. The Zone allocator will be upgradeable to be able
to use per CPU-pools, and has more intelligent usage of SPLs. Additionally,
it has reasonable stats gathering capabilities, while making most calls
inline.

John Hood, who originally made our IDE DMA stuff work :-).
I have run tests with 7 IDE drives connected to my system, all in DMA
mode, with no errors. Modulo any bugs, this stuff makes IDE look
really good (within it's limitations.)

As a side effect, broken enhanced floppy controllers that sometimes

Hide the bogus FDC ``chip type'' display behind a (mostly) undocumented

to handle 2.88 MB controllers, we have to redo the chip detection, by
now just leave it hidden.

We aren't sure if this new code and the old sound code will co-exist in a
