* This is new scsi lld device driver from LSI supporting the SAS 2.0
  standard. I have split patchs by filename.

* Here is list of new 6gb host controllers:

  LSI SAS2004
  LSI SAS2008
  LSI SAS2108
  LSI SAS2116

* Here are the changes in the 4th posting of this patch set:

(1) fix compile errors when SCSI_MPT2SAS_LOGGING is not enabled
(2) add mpt2sas to the SCSI Mid Layer Makefile
(3) append mpt2sas_ to the naming of all non-static functions
(4) fix oops for SMP_PASSTHRU
(5) doorbell algorithm imported changes from windows driver

* Here are the changes in the 3rd posting of this patch set:

(1) add readl following writel from the function that disables interrupts
(2) replace 0xFFFFFFFFFFFFFFFFULL with ~0ULL
(3) when calling pci_enable_msix, only pass one msix entry (instead of 15).
(4) remove the "current HW implementation uses..... " comment in the sources
(5) merged bug fix for SIGIO/POLLIN notifcation; reported by the storlib team.

config SCSI_MPT2SAS
tristate "LSI MPT Fusion SAS 2.0 Device Driver"
depends on PCI && SCSI
select SCSI_SAS_ATTRS
---help---
This driver supports PCI-Express SAS 6Gb/s Host Adapters.
config SCSI_MPT2SAS_MAX_SGE
int "LSI MPT Fusion Max number of SG Entries (16 - 128)"
depends on PCI && SCSI && SCSI_MPT2SAS
default "128"
range 16 128
---help---
This option allows you to specify the maximum number of scatter-
gather entries per I/O. The driver default is 128, which matches
SAFE_PHYS_SEGMENTS. However, it may decreased down to 16.
Decreasing this parameter will reduce memory requirements
on a per controller instance.
config SCSI_MPT2SAS_LOGGING
bool "LSI MPT Fusion logging facility"
depends on PCI && SCSI && SCSI_MPT2SAS
---help---
This turns on a logging facility.
