in the per-device kthread. This ensures that synchronisation with
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.

aic7xxx.seq:
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.
aic7xxx.c:
aic7xxx.h:
Change ahc/ahd_upate_neg_request() to take a "negotiation
type" enum that allows us to negotiate:
o only if the goal and current parameters differ.
o only if the goal is non-async
o always - even if the negotiation will be for async.
aic7xxx.seq:
Reset the FIFO whenever a short CDB transfer occurs
so that the FIFO contents do not corrupt a future CDB
transfer retry.
Add support for catching the various protocol violations
handled by ahc_handle_protocol_violation.
Reformat some comments.
aic7xxx.c:
aic7xxx.h:
Just for safety, have the aic7xxx driver probe
the stack depth.
aic7xxx.c:
aic7xxx.h:
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
value used to backfill the stack if entries are overwritten
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.

converting from individual vnode locks to the snapshot
lock, be sure to pass any waiting processes along to the
new lock as well. This transfer is done by a new function
in the lock manager, transferlockers(from_lock, to_lock);
Thanks to Lamont Granquist <lamont@scriptkiddie.org> for
his help in pounding on snapshots beyond all reason and
finding this deadlock.

1) Release the snapshot file lock while suspending the system. Otherwise
a process trying to read the lock may block on its containing directory
preventing the suspension from completing. Thanks to Sean Kelly
<smkelly@zombie.org> for finding this deadlock.
2) Replace some bdwrite's with bawrite's so as not to fill all the
buffers with dirty data. The buffers could not be cleaned as the
snapshot vnode was locked hence the system could deadlock when
making snapshots of really massive filesystems. Thanks to
Hidetoshi Shimokawa <simokawa@sat.t.u-tokyo.ac.jp> for figuring
this out.

1) Record all device events when devctl is enabled, rather than just when
devd has devctl open. This is necessary to prevent races between when
a device arrives, and when devd starts.
2) Add hw.bus.devctl_disable to disable devctl, this can also be set as a
tunable.
3) Fix async support. Reset nonblocking and async_td in open. remove
async flags.
4) Free all memory when devctl is disabled.

Previous kernels unwantingly depended on this mapping, but as
of version 1.123 of src/sys/ia64/ia64/machdep.c this dependency
has been removed. Consequently, one has to update the kernel
before updating the loader. The documented/recommended upgrade
will suffice in this case.
Due to a visible (from the kernels point of view) change in
behaviour, bump the loader version number from 0.3 to 1.0.
