lpfc: Fix scsi prep dma buf error.

2015-09-02T13:49:54+00:00

commit 5116fbf136ea21b8678a85eee5c03508736ada9f upstream.

Didn't check for less-than-or-equal zero. Means we may later call
scsi_dma_unmap() even though we don't have valid mappings.

lpfc: Add iotag memory barrier

2015-07-30T11:21:20+00:00

commit 27f344eb15dd0da80ebec80c7245e8c85043f841 upstream.

Add a memory barrier to ensure the valid bit is read before
any of the cqe payload is read. This fixes an issue seen
on Power where the cqe payload was getting loaded before
the valid bit. When this occurred, we saw an iotag out of
range error when a command completed, but since the iotag
looked invalid the command didn't get completed to scsi core.
Later we hit the command timeout, attempted to abort the command,
then waited for the aborted command to get returned. Since the
adapter already returned the command, we timeout waiting,
and end up escalating EEH all the way to host reset. This
patch fixes this issue.

Pull misc SCSI driver updates from James Bottomley:
 "This patch set is a set of driver updates (megaraid_sas, fnic, lpfc,
  ufs, hpsa) we also have a couple of bug fixes (sd out of bounds and
  ibmvfc error handling) and the first round of esas2r checker fixes and
  finally the much anticipated big endian additions for megaraid_sas"
