Add support for physical LUN segmentation (virtual LUNs) to device
driver supporting the IBM CXL Flash adapter. This patch allows user
space applications to virtually segment a physical LUN into N virtual
LUNs, taking advantage of the translation features provided by this
adapter.

Add superpipe supporting infrastructure to device driver for the IBM CXL
Flash adapter. This patch allows userspace applications to take advantage
of the accelerated I/O features that this adapter provides and bypass the
traditional filesystem stack.

This patch addresses several issues found since originally submitting
support for legacy I/O on the IBM CXLflash adapter.
These include:
- proper TMF handling
- reworking sysfs attributes/handler as suggested by Shane Seymour
- fixing cleanup bugs and potential memory leaks
- spelling fixes
-
This patch set is intended for the 4.3 release and adds support for
error recovery and the superpipe features provided by the IBM CXL
Flash adapter. The superpipe function was originally presented in an
RFC patch set in late April. To aid with the review of the superpipe
portion of these enhancemen

A set of three fixes for the ipr driver and one fairly major one for
memory leaks in the mq path of SCSI.
