More fallout from the writeback fixes: debug register transfer
instructions do their own writeback and thus need to disable the general
writeback mechanism.
This fixes oopses and some guest failures on AMD machines (the Intel
variant decodes the instruction in hardware and thus does not need
emulation).

Alan Cox suggested that the solution to the FIXMEs in pata_icside is
to use a private postreset method to detect the lack of devices on a

This patch implements such a method, and removes the hard coded
disable of port 0. Tested as working.

check_condition code-path was similar but more
complicated to Reset. It went like this:
1. extra space was allocated at aha152x_scdata for mirroring
scsi_cmnd members.
2. At aha152x_internal_queue() every not check_condition
(REQUEST_SENSE) command was copied to above members in
case of error.
3. At busfree_run() in the DONE_CS phase if a Status of
SAM_STAT_CHECK_CONDITION was detected. The command was
re-queued Internally using aha152x_internal_queue(,,check_condition,)
The old command members are over written with the
REQUEST_SENSE info.
4. At busfree_run() in the DONE_CS phase again. If it is a
check_condition command, info was restored from mirror
made at first call to aha152x_internal_queue() (see 2)
and the command is completed.
What I did is:
1. Allocate less space in aha152x_scdata only for the 16-byte
original command. (which is actually not needed by scsi-ml
anymore at this stage. But this is to much knowledge of scsi-ml)
2. If Status == SAM_STAT_CHECK_CONDITION, then like before
re-queue a REQUEST_SENSE command. But only now save original
command members. (Less of them)
3. In aha152x_internal_queue(), just like for Reset, use the
check_condition hint to set differently the working members.
execute the command.
4. At busfree_run() in the DONE_CS phase again. restore needed
members.
While at it. This patch fixes a BUG. Old code when sending
a REQUEST_SENSE for a failed command. Would than return with
cmd->resid == 0 which was the status of the REQUEST_SENSE.
The failing command resid was lost. And when would resid
be interesting if not on a failing command?

What Reset code was doing: Save command's important/dangerous
Info on stack. NULL those members from scsi_cmnd.
Issue a Reset. wait for it to finish than restore members
and return.
What I do is save or NULL nothing. But use the "resetting"
hint in aha152x_internal_queue() to NULL out working members
and leave struct scsi_cmnd alone.
The indent here looks funny but it will change/drop in last
patch and it is clear this way what changed.

hunk by hunk:
- CHECK_CONDITION is what happens to cmnd->status >> 1
or after status_byte() macro. But here it is used
directly on status which means 0x1 which is an undefined
bit in the standard. And is a status that will never
return from a target.
- in busfree_run at the DONE_SC phase we have 3 distinct
operation:
1-if(DONE_SC->SCp.phase & check_condition)
The REQUEST_SENSE command return.
- Restore original command
- Than continue to operation 3.
2-if(DONE_SC->SCp.Status==SAM_STAT_CHECK_CONDITION)
A regular command returned with a status.
- Internally re-Q a REQUEST_SENSE.
- Do not do operation 3.
3-
- Complete the command and return it to scsi-ml
So the 0x2 in both these operations (1,2) means the scsi
check-condition status, hence SAM_STAT_CHECK_CONDITION
- Here the code asks about !(DONE_SC->SCp.Status & not_issued)
but "not_issued" is an enum belonging to the "phase" member
and not to the Status returned from target. The reason this
works is because not_issued==1 and Also CHECK_CONDITION==1
(remember from hunk 1). So actually the code was asking
!(DONE_SC->SCp.Status & CHECK_CONDITION). Which means
"Has the status been read from target yet?"
Staus is read at status_run(). "not_issued" is
cleared in seldo_run() which is usually earlier than
status_run().
So this patch does nothing as far as assembly is concerned
but it does let the reader understand what is going on.

Our current implementation has a generic set of barrier functions that
go through the SCSI driver model. Realistically, this is unnecessary,
because the only device that can use barriers (sd) can set the flush
functions up at probe or revalidate time. This patch pulls the barrier
functions out of the mid layer and scsi driver model and relocates them
directly in sd.

The device would not resume properly if it was shutdown before the system
was suspended. In such scenario where the netif_running state is 0,
bnx2_suspend() would not save the PCI state and so the memory enable bit
and bus master enable bit would be lost.
We fix this by always saving and restoring the PCI state in
bnx2_suspend() and bnx2_resume() regardless of netif_running() state.

There is a couple of subtle checks which were needed to handle ptracing from
the same thread group. This was deprecated a long ago, imho this code just
complicates the understanding.
And, the "->parent->signal->flags & SIGNAL_GROUP_EXIT" check in exit_notify()
is not right. SIGNAL_GROUP_EXIT can mean exec(), not exit_group(). This means
ptracer can lose a ptraced zombie on exec(). Minor problem, but still the bug.
