* 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.
