3151367f87 SCSI for-linus on 20121002
This is a large set of updates, mostly for drivers (qla2xxx [including support
 for new 83xx based card], qla4xxx, mpt2sas, bfa, zfcp, hpsa, be2iscsi, isci,
 lpfc, ipr, ibmvfc, ibmvscsi, megaraid_sas).  There's also a rework for tape
 adding virtually unlimited numbers of tape drives plus a set of dif fixes for
 sd and a fix for a live lock on hot remove of SCSI devices.
 
 This round includes a signed tag pull of isci-for-3.6

e67f13212a [SCSI] qla2xxx: remove unnecessary reads of PCI_CAP_ID_EXP
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).
