v1->v2
- removed undefined entries from mpi30_type.h
- removed DRV_CMD_CALLBACK typedef
- Use IRQF_SHARED instead of IRQF_ONESHOT
- Use READ_ONCE, WRITE_ONCE while accessing operational request
queue consumer index
- removed in_interrup()
- remove pr_cont.
- move some code from error handling to device handling patch.
- used direct values instead of macro MPI3_SECTOR_SIZE_XYZ
- Add Hannes's reviewed-tag to appropriate patches
- Add Reported-by kernel test robot <lkp@intel.com> to appropriate
patches.

This patch series covers logical patches of the new device driver for the
MPI3MR high performance storage I/O & RAID controllers (Avenger series).
The mpi3mr has true multiple h/w queue interfacing like nvme.

See more info -
https://www.spinics.net/lists/linux-scsi/msg147868.html

The controllers managed by the mpi3mr driver are capable of reaching a
very high performance numbers compared to existing controller due to the
new hardware architectures. This Driver is tested with the internal
versions of the MPI3MR I/O & RAID controllers.

Patches are logical split mainly for better code review. Full patch set is
required for functional stability of this new driver.
