After m68k's task_thread_info() doesn't refer to current,
it's possible to remove sched.h from interrupt.h and not break m68k!
Many thanks to Heiko Carstens for allowing this.

CACHE command
Normally In HBA reset path MPT driver will flush existing work in current work
queue (mpt/0) . This is just a dummy activity for MPT driver point of
view, since HBA reset will turn off Work queue events.
It means we will simply returns from work queue without doing anything.
But for the case where Work is already done (half the way), we have to have
that work to be done.
Considering above condition we stuck forever since Deadlock in scsi midlayer
and MPT driver. sd_sync_cache() will wait forever since HBA is not in
Running state, and it will never come into Running state since
sd_sync_cache() is called from HBA reset context.
Now new code will not wait for half cooked work to be finished
before returning from HBA reset.
Once we are out of HBA reset, EH thread will change host state to running from
recovery and work waiting for running state of HBA will be finished.
New code is turning ON firmware event from another special work called
Rescan toplogy.

The reason for this change is there is a data corruption when four different
physical memory regions in the 36GB to 37GB region are
accessed. This is only affecting 1078.
The solution is we need to use different addressing when filling in
the scatter gather table for the effected memory regions. So instead
of snooping on all four different memory holes, we treat any physical
addresses in the 36GB address with the same algorithm.
The fix is explained below
1) Ensure that the message frames are NOT located in the trouble
region. There is no remapping available for message frames, they must
be allocated outside the problem region.
2) Ensure that Sense buffers are NOT in the trouble region. There is
no remapping available.
3) Walk through the SGE entries and if any are inside the trouble region
then they need to be remapped as discussed below.
1) Set the Local Address bit in the SGE Flags field.
MPI_SGE_FLAGS_LOCAL_ADDRESS
2) Ensure we are using 64-bit SGEs
3) Set MSb (Bit 63) of the 64-bit address, this will indicate buffer
location is Host Memory.

In commit c3a4d78c580de4edc9ef0f7c59812fb02ceb037f, while introducing
rq->resid_len, the default value of residue count was changed from
full count to zero. The conversion was done under the assumption that
when a request fails residue count wasn't defined. However, Boaz and
James pointed out that this wasn't true and the residue count should
be preserved for failed requests too.
This patchset restores the original behavior by setting rq->resid_len
to blk_rq_bytes(rq) on request start and restoring explicit clearing
in affected drivers. While at it, take advantage of the fact that
rq->resid_len is set to full count where applicable.
* ide-cd: rq->resid_len cleared on pc success
* mptsas: req->resid_len cleared on success
* sas_expander: rsp/req->resid_len cleared on success
* mpt2sas_transport: req->resid_len cleared on success
* ide-cd, ide-tape, mptsas, sas_host_smp, mpt2sas_transport, ub: take
advantage of initial full count to simplify code
Boaz Harrosh spotted bug in resid_len initialization. Fixed as
suggested.

rq->data_len served two purposes - the length of data buffer on issue
and the residual count on completion. This duality creates some
headaches.
First of all, block layer and low level drivers can't really determine
what rq->data_len contains while a request is executing. It could be
the total request length or it coulde be anything else one of the
lower layers is using to keep track of residual count. This
complicates things because blk_rq_bytes() and thus
[__]blk_end_request_all() relies on rq->data_len for PC commands.
Drivers which want to report residual count should first cache the
total request length, update rq->data_len and then complete the
request with the cached data length.
Secondly, it makes requests default to reporting full residual count,
ie. reporting that no data transfer occurred. The residual count is
an exception not the norm; however, the driver should clear
rq->data_len to zero to signify the normal cases while leaving it
alone means no data transfer occurred at all. This reverse default
behavior complicates code unnecessarily and renders block PC on some
drivers (ide-tape/floppy) unuseable.
This patch adds rq->resid_len which is used only for residual count.
While at it, remove now unnecessasry blk_rq_bytes() caching in
ide_pc_intr() as rq->data_len is not changed anymore.
Boaz : spotted missing conversion in osd
Sergei : spotted too early conversion to blk_rq_bytes() in ide-tape
[ Impact: cleanup residual count handling, report 0 resid by default ]
