mddestroy() succeeds even if the kthread was not waiting in tsleep()
at the time of the wakeup(). Among other things, this fixes the
problem of mdconfig getting stuck when an attempt is made to use a
zero-length file as a vnode-type backing store.

Bring in the protocol violation handler from the U320
driver and replace the NO_IDENT sequencer interrupt code
with the PROTO_VIOLATION code. Support for this code
required the following changes:
SEQ_FLAGS:
IDENTIFY_SEEN -> NOT_IDENTIFIED
Added NO_CDB_SENT
SCB_CONTROL:
TARGET_SCB == STATUS_RCVD for initiator mode
scb->flags:
Added SCB_TARGET_SCB since we cannot rely on
TARGET_SCB as a target/initiator differentiator
due to it being overloaded in initiator mode to
indicate that status has been received.
aic7xxx.seq:
Move data fifo CLRCHN to mesgin_rdptrs which is a safer
location for doing this operation. This also saves a
sequencer instruction.

Change ahc/ahd_upate_neg_request() to take a "negotiation

o only if the goal and current parameters differ.

o always - even if the negotiation will be for async.

Reset the FIFO whenever a short CDB transfer occurs

transfer retry.

Save and restore stack contents during diagnostics.
Some chip variants overwrite stale entries on a
stack "pop".
Don't use 0 to probe the stack depth. 0 is the typical

on a "pop".
aic7xxx.h:
Add a missing typedef.
Collapse SCB flag entries so they are bit contiguous.
Add AHD_ULTRA2_XFER_PERIOD for narrow fallback calculations
aic7xxx.c:
Don't panic (as a diagnostic to catch bugs) if we decided to
force the renegotiation of async even if we believe we are
already async. This should allow us to negotiate async instead
of the full user goal rate during startup if bus resets are
disabled.
Add a space to the end of the ahc/ahd_print_devinfo routines
so that it behaves as expected by the code that uses it.
Only force a renegotiation on a selection timeout
if the SCB was valid. Doing otherwise may be dangerous
as the connection was not valid for an unknown reason.
Add additional diagnostic output to ahc_dump_card_state(),
and have it use the register pretty printing functions.
Update ahc_reg_print() to handle a NULL cur_col.
Add a newline to ahc_dump_card_state() output.
Bring back "use_ppr". We need to use_ppr anytime
doppr is true or we have non-zero protocol options.
The later case was not handled in the recent removal
of use_ppr.
Move a comment and remove a useless clearing of use_ppr.
Don't disable ENBUSFREE when single stepping on
a DT capable controller. We cannot re-enable unexpected
busfree detection, so we must clear BUSFREE on each
step instead.
Correct the lookup of the SCB ID in ahc_handle_proto_error.
Remove a diagnostic printf.
Remove unecessary restoration of the STACK for older
chips.

1. Detect the revision of the Rhine chip we're using.
2. Use the force reset command on revisions which support
it whenever the normal reset command fails.
This should solve a wide range of "my vr0 locks up with reset
failed messages" problems. (Although the root causes should
be eventually tracked down.)

to PCI bridge can be read be evaluating the _BBN method of the host to PCI
device. Unfortunately, there appear to be some lazy/ignorant/moronic/
whatever BIOS writers that return 0 for _BBN for all host to PCI bridges in
the system. On a system with a single host to PCI bridge this is not a
problem as the child bus of that single bridge will be bus 0 anyway.
However, on systems with multiple host to PCI bridges and l/i/m/w BIOS
writers this is a major problem resulting in all but the first host to
PCI bridge failing to attach. So, this adds a workaround.
If the _BBN of a host to PCI bridge is zero and pcib0 already exists
and is not us, the we use _ADR to look up our PCI function and slot
(we currently assume we are on bus 0) and use that to call
host_pcib_get_busno() to try and extract our bus number from config
registers on the host to PCI bridge device. If that fails, then we make
an evil assumption that ACPI's _SB_ namespace lays out the host to PCI
bridges in ascending order and use our pcib unit number as our bus
number.
