[SCSI] mpt2sas v00.100.11.15
* 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.
* Here are the changes in the 2nd posting of this patch set:
(1) use little endian types in the mpi headers
(2) merged in bug fix's from inhouse drivers.
