2015-06-29lpfc: Add iotag memory barrierJames Smart
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.

2013-12-19[SCSI] lpfc: Fix wrong assignment in lpfc_debugfs.cFelipe Pena
On lpfc_debugfs_initialize function the dumpHostSlim member setup happens when 'phba->sli_rev < LPFC_SLI_REV4' is true, however when it is false NULL has been assigned to debug_dumpHBASlim instead of debug_dumpHostSlim.

2013-10-25[SCSI] lpfc 8.3.43: Fixed not processing task management IOCB response statusJames Smart
This patch implements the changes requested by Jeremy Linton: http://marc.info/?l=linux-scsi&m=136242124409687&w=2 The patch revises the command issuing behavior, detecting cases where the Task Mgmt command may have completed but with a non-successful status, which it previously treated as a successful TMF. The patch also corrects a flushing of I/O that was done which should only be done on successful TMF completion.

2013-10-25[SCSI] lpfc: remove unnecessary read of PCI_CAP_ID_EXPJon Mason
The PCIE capability offset is saved during PCI bus walking. It will remove an unnecessary search in the PCI configuration space if this value is referenced instead of reacquiring it. Also, pci_is_pcie is a better way of determining if the device is PCIE or not (as it uses the same saved PCIE capability offset).

Since commit 0998d0631001288a5974afc0b2a5f568bcdecb4d (device-core: Ensure drvdata = NULL when no driver is bound), the driver core clears the driver data to NULL after device_release or on probe failure. Thus, it is not needed to manually clear the device driver data to NULL.
