ported the miibus support to -current, though it was mostly harmless.
We now set the vendor code to the new value ED_VENDOR_LINKSYS in
ed_pccard_Linksys() at probe time. Then ed_pccard_attach() checks
the vendor code, and sets up the miibus if appropriate.

During context restore, load dr7 in such a way as to not
disturb reserved bits.
machdep.c: Don't explicitly disallow the setting of the reserved bits
in dr7 since we now keep from setting them when we load dr7
from the PCB.
This allows one to write back the dr7 value obtained from

If bus_dma will give us addresses > 32 bits, setup our dma tag
to accept up to 39bit addresses.
aic7770.c:
Update the softc directly rather than use an intermediate
"probe_config" structure.
aic7xxx.c:
Complete core work to support 39bit addresses for bulk data
dma operations. Controller data structures still must reside
under the 4GB boundary to reduce code/data size in the sequencer
and related data structures. This has been tested under Linux
IA64 and will be tested on IA64 for FreeBSD as soon as our port
can run there.
Add bus dmamap synchronization calls around manipulation of
all controller/kernel shared host data structures.
Implement data pointer reinitialation for a second data phase
in a single connection in the kernel rather than bloat the
sequencer. This is an extremely rare operation (does it ever
happen?) and the sequencer implementation was flawed for some
of the newest chips.
Don't ever allow our target role to initiate a PPR. This
is forbidden by the SCSI spec.
Add a few missing endian conversions in the ignore wide pointers
code. The core has been tested on the PPC under Linux and should
work for FreeBSD PPC. As soon as I can test the OSM layer for
FreeBSD PPC, I will.
Move some of ahc_softc_init() into ahc_alloc() now that the
probe_config structure is gone.
Add a 4GB boundary condition on all of our dma tags. 32bit
DAC under PCI only works on a single 4GB "page". Although
we can cross 4GB on a true 64bit bus, the card won't always
be installed in one and we can save code space and cost in
implementing high address support by assuming the high DWORD
address will never change.
Add diagnostics to ahc_search_qinfifo().
Correct a target mode issue with bus resets. To avoid an
interrupt storm from a malicious third party holding the
reset line, the sequencer would defer re-enabling the reset
interrupt until either a select-out or select-in. Unfortunately,
the select-in enable bit is cleared by a bus reset, so a second
reset will render the card deaf to an initiator's attempts to
contact it. We now re-enable bus reset interrupts immediately
if the target role is enabled.
aic7xxx.h:
Remove struct ahc_probe_config.
SCB's now contain a pointer to the sg_map_node so we can perfrom
bus dma sync operations on the SG list prior to queuing a command.
aic7xxx.reg:
Register the Perforce ID for this file with the VERSION keyword
so it is printed in generated files.
Add the DSCOMMAND1 register which is used to access the high
DWORD of address bits.
Add the data pointer reinitialize sequencer interrupt code.
aic7xxx.seq:
Register the Perforce ID for this file with the VERSION keyword
so it is printed in generated files.
Remove code to re-enable the bus reset interrupt after a select-in.
In target mode we cannot defer this operation as ENSELI is cleared
by a bus reset.
Complete 39bit support.
Generate a sequencer inteerrupt rather than handle the data
pointers re-initialitation in the sequencer.
Inline the "seen identify" assertion to save a few cycles.
Short circuit the update of our residual data if we have
fully completed a transfer. The residual is correct from
our last S/G load operation.
Short circuit full SDPTR processing if the residual is 0.
Just mark the transfer as complete.
aic7xxx_93cx6.c:
Synchronize perforce IDs.
aic7xxx_freebsd.c:
Complete untested 39bit support.
Add missing endia conversions.
Clear our residuals prior to starting a command. The
update residual code in the core only sets the residual
if there is one.
aic7xxx_freebsd.h:
Modeify ahc_dmamap_sync() macros to take an offset and a length.
This is how sync operations are performed in NetBSD, and we should
update our bus dma implementation to match.
aic7xxx_inline.h:
Add data structure synchronization helper functions.
Fix a bug in ahc_intr() where we would not clear our unsolicited
interrupt counter after running our PCI interrupt handler. This
may have been the cause of the spurious PCI interrupt messages.
aic7xxx_pci.c:
Adjust for loss of probe_config structure.
Guard against bogus 9005 subdevice information as seen on some
IBM MB configurations.
Add 39bit address support.

removing a modules directory is not all that uncommon a mistake,
and finding a file with the contents of the last module installed

Basically, if you're halting or you're rebooting, you should
tell all other processors to halt first. Define IPI_HALT- IPI_STOP
is not what we want for this purpose, which will call prom_halt(0)
on receipt.
The processor running the halt or reboot wil send an IPI_HALT to all
other processors, delay a bit, then continue to do what what it was
planning on doing (prom_halt({0|1})).

. Sanitize comments. Convert them into the style(9)-recommended
multi-line form, make them sentences where apprpriate, etc.
. Declare all functions on top, and declare them in the order they
appear in the file. This order is totally chaotic, but Bruce

- Kill the ready queue, and handle a busy response to mly_start in callers
rather than deferring the command.
- Improve our interaction with CAM:
- Don't advertise physical channels as SCSI busses by default.
- use the SIM queue freeze capability rather than queueing CDBs internally.
- force bus reprobe at module load time.
- Clean up more resources in mly_free.
- Tidy up debugging levels.
- Tidy up handling of events (mostly just code cleanliness).
- Use explanatory macros for operations on bus/target/channel numbers.
extra getblk/brelse sequence for each lookup. We already had this
buf in ufsdirhash_lookup(), so there was no point in brelse'ing it
only to have the caller immediately reaquire the same buffer.
This should make the case of sequential lookups marginally faster;
in my tests, sequential lookups with dirhash enabled are now only
around 1% slower than without dirhash.
This should help us in nieve benchmark "tests".
It seems a wide number of people think 32k buffers would not cause major
issues, and is in fact in use by many other OS's at this time. The
receive buffers can be bumped higher as buffers are hardly used and several
research papers indicate that receive buffers rarely use much space at all.
