Linus Torvalds abf04af74a SCSI for-linus on 20140613

 sparse).

James Smart 73d91e503a [SCSI] lpfc 8.3.27: Miscellanous logic and interface fixes
Miscellanous logic and interface fixes

- Fix lpfc_init_vfi_cmpl to check the interface type for interface type 0
  before parsing the results.
- Cast uint32_t values that are multiplied to uint64_t before the
  multiplication.
- Instead of "break" statement when PCI read returned error, use the goto
  statement to the end of the routine after setting return value
- moved the msleep(10) to the beginning of the wait loop for checking the
  SLIPort_Status register
- Added the code to follow the existing wait for SLIPort_Status register RDY,
  ERR, and RN bits to be set by the port before proceeding to perform PCI
  function reset.
- Do not override ulpCt_h and ulpCt_l for SLI 4 ports.
- For vport delete, call lpfc_nlp_put when the vport's vpi state is not
  marked with VPI_REGISTERED.
- Added missed fields into the driver's Controller Attributes Structure
- Changed ringing EQ/CQ/RQ doorbell register to be dependent on the size
  of the queue.
- Return -EACCES in issue_reset if cfg_enable_hba_reset is zero.
- Added new logging flag LOG_FCP_UNDER 0x00040000 to qualify underrun logging.
- Add a check in the fabric name display routine to display 0 if the port
  state is <= FLOGI.
- Add a check to the switch statement in lpfc_decode_firmware_rev to check
  for an 'X'.

James Smart bf08611bcc [SCSI] lpfc 8.3.26: Fix issues pertaining to SCSI/FC protocol.
Fix issues pertaining to SCSI/FC protocol.

- Allow frames destined to 0xFFFFFE to be processed by the driver by matching
  that DID with the physical port.
- Call lpfc_sli_issue_iocb with context1 set to ndlp
- In echo command accept function, adjust memcpy to limit memcpy to 1K
- Set LPFC_SLI3_BG_ENABLED properly upon completion.
- Skip the INIT_VFI call in lpfc_register_fcf if the FCF is already
  registered and go immediately to initial flogi.
- use "status" variable instead of "ret" variable to hold the return of the
  fc_block_scsi_eh.

James Smart 7d791df730 [SCSI] lpfc 8.3.25: Add FCF priority failover functionality
This patch implements a new FCF failover policy for the lpfc driver. It
allows the driver to choose which FCF to failover to based on the FCF
priority. This patch also introduces a new sysfs parameter
(fcf_failover_policy) to allow the user to choose which FCF failover policy
to use.

Fabric and Target Discovery Fixes

- Clear FC_VPORT_NEEDS_INIT_VPI flag during completion of REG_VFI mailbox
  command.
- Prevent SLI3 Code from unregistering the physical VPI.
- Add an else clause to the code that checks and sets
  sp->cmn.request_multiple_Nport to clear the bit.
- Remove a redundant mbox free.
- Modified lpfc_sli4_async_fip_evt to pass in physical VPI toi
  lpfc_find_vport_by_vpid function.
- Modified lpfc_find_vport_by_vpid to translate physical VPI to logical VPI
  before comparing with vport VPI.

James Smart 0558056c1e [SCSI] lpfc 8.3.24: Miscellaneous Fixes and Corrections
Miscellaneous Fixes and Corrections
- Remove the memset in the lpfc_sli4_remove_rpi_hdrs call.
- Correct swapping of SGE word 2 relative to offset value
- Reorganize CQ and EQ usage to comply with SLI4 Specification.
- Expand the driver to check the rn bit. Only detect an error if the error bit
  is set and the RN bit is NOT set.
- If mailbox completion code is not success AND the mailbox status is success,
  then and only then will the driver overwrite the mailbox status.
- When driver initializing device, if the device is on a PCIe bus, set
  PCI's "needs fundamental reset" bit so that EEH uses fundamental reset
  instead of hot reset for recovery.
- Prevent driver from using new WWN when changed in firmware (until driver
  reload)
- When HBA reports maximum SGE size > 0xffffffff (infinite), override
  with 0x80000000.
- Fixed potential missed SLI4 device initialization failure conditions.
- Added 100ms delay before driver action following IF_TYPE_2 function reset.
- Reverted patch to UNREG/REG on PLOGI to mapped/unmapped node.
- Add a check for the CVL received flag in the fcf inuse routine to avoid
  unregistering the fcf if Devloss fires before Delay discover timer fires.
