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. Signed-off-by: NKashyap Desai <kashyap.desai@lsi.com> Signed-off-by: NJames Bottomley <James.Bottomley@suse.de>

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.

Until now we have had a 1:1 mapping between storage device physical block size and the logical block sized used when addressing the device. With SATA 4KB drives coming out that will no longer be the case. The sector size will be 4KB but the logical block size will remain 512-bytes. Hence we need to distinguish between the physical block size and the logical ditto. This patch renames hardsect_size to logical_block_size. Signed-off-by: NMartin K.

In commit c3a4d78c, 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.
