      [SCSI] lpfc 8.3.24: Extended hardware support and support dump images · c0c11512
      由 James Smart 提交于 
      Extended hardware support and support dump images:
- Make the size to be MAILBOX_SYSFS_MAX (4096) so that it allows the maximum
  sysfs binary access interface possible.
- Add ids and model names for new hardware
- Add capability of inducing SLI4 firmware dump obj file

      [SCSI] lpfc 8.3.24: Miscellaneous Fixes and Corrections · 0558056c
      由 James Smart 提交于 
      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.

      SCSI host lock push-down · f281233d
      由 Jeff Garzik 提交于 
      Move the mid-layer's ->queuecommand() invocation from being locked
with the host lock to being unlocked to facilitate speeding up the
critical path for drivers who don't need this lock taken anyway.

The patch below presents a simple SCSI host lock push-down as an
equivalent transformation.  No locking or other behavior should change
with this patch.  All existing bugs and locking orders are preserved.

Additionally, add one parameter to queuecommand,
	struct Scsi_Host *
and remove one parameter from queuecommand,
	void (*done)(struct scsi_cmnd *)

Scsi_Host* is a convenient pointer that most host drivers need anyway,
and 'done' is redundant to struct scsi_cmnd->scsi_done.

Minimal code disturbance was attempted with this change.  Most drivers
needed only two one-line modifications for their host lock push-down.
