- The 1st (preparse_mp_table()) counts the number of cpus, busses, etc. and
records the LOCAL and IO APIC addresses.
- The 2nd pass (parse_mp_table()) does the actual parsing of info and recording
into the incore MP table.
This will allow us to defer the 2nd pass untill malloc() & private pages
are available (but thats for another day!).
When a panic occurs early in the SMP boot process 'cpunumber()' hangs,
causing the panic string to be lost. Now the system appears to hang
in 'breakpoint()', but at least the user sees the panic string before the
hang.
switch. I needed 'LINT' to compile for other reasons so I kinda got the
blood on my hands. Note: I don't know how to test this, I don't know if
it works correctly.
Don't search for interface addresses matching interface "NULL"
it's likely to cause a page fault..
this can be triggered by the ipfw code rejecting a locally generated
packet (e.g. you decide to make some network unreachable by local users)

to:
printf( "xxxxx\n" );
panic( "\n" );
For some as yet undetermined reason the argument to panic() is often NOT
printed, and the system sometimes hangs before reaching the panic printout.
So we hopefully at least print some useful info before the hang, as oppossed to
leaving the user clueless as to what has happened.

change the layout anyway.
Recompile ps, top, libutil and all that.

Remove "setdefs.h" and arrange to generate it automatically at
ELF kernel build time.
"gensetdefs.c" is a utility which scans a set of ELF object files
and outputs a line ``DEFINE_SET(name, length);'' for each linker
set that it finds. When generating an ELF kernel, this is run just
before the final link to generate "setdefs.h".
Remove the init_sets() function from "setdef0.c", and its call from
"machdep.c". Since "gensetdefs.c" calculates the length of each
set, it is no longer necessary in an ELF kernel to count the set
elements at kernel initialization time. Also remove "set_of_sets"
which was used for this purpose.
Link "setdef0" and "setdef1" into the kernel only if building for
ELF. Since init_sets() is no longer used, there is no need to link
them into an a.out kernel.
all uses of it with the equivalent calls to setbits().
This change incidentally eliminates a problem building ELF kernels
that was caused by SETBITS.

1) Adjust NFRAMES from 16 to 8 per 16k of memory.
2) Acknowledge interrupts to the card early in the interrupt
handler before processing the event that caused the interrupt.
This frees the card to process addtional events instead of
waiting for the driver to finish handling events.
3) Changed the initialization of the transmit buffers to be a
loop so that the number of buffers can be more easily changed.
4) Moved the code to take the adapter out of loop back mode to just
before we enable the receiver.
I also made the driver dynamically size its resource arrays at attach
time so that we can take full advantage of adapters with more than 16k
of memory.
Richard has some other changes he's working on to improve performance,

full implementation of the sate machine as described in RFC1661, and
provides support for plugging in various control protocols. I needed
this to provide PPP support for the BISDN project (right now).
Unfortunatley, while the existing API was almost up to the point, i
needed one minor API change in order to decouple the this-layer-
started and this-layer-finished actions from the respective Up and
Down events of the lower layer. This requires two additional lines in
the attach routines of all existing lower layer interface drivers that
are using syncPPP (shortcutting these actions and events). Apart from
this, i believe i didn't change the API of all this, so everything
should plug in without too many hassles. Please report if i broke
something in the existing drivers.
For a list of features (including new ones like dial-on-demand), and
things still to be done, please refer to the man page i'll commit asap.

- remove all calls to scsi_stop_unit(). Some drives refuse commands when
stopped. This will fix the 'device not configured' message which was
cleared after opening/closing the tray.
- Never set the logical block address in the scsi_cmd struct when writing.
The computation was bogus for block sizes not a multiple of DEV_BSIZE.
(the bug is still there in the READ case)
- reset the block size to the 2048 bytes in finalize_track() track to avoid
an error when mounting a disk after an audio write.
- remove the WORMIOCQUIRKSELECT ioctl. Quirks are now recorded at probe time
(see scsiconf.c)
- change and expand the argument to the WORMIOCPREPTRACK ioctl. It now possible
to select more track options (copy bits, ISRC codes, track type,
track number)
- add an error handler to catch false errors (warnings in fact) and record
the error type.
- add an ioctl call (WORMIOERROR) to get more information on the nature of the
error when a command or a write failed.
- add an ioctl call (WORMIOCFINISHTRACK) to finalize a track without closing
the device (closing the device still finalize the track if the command was
not performed)
