This patch set is a set of driver updates (megaraid_sas, fnic, lpfc, ufs,
hpsa) we also have a couple of bug fixes (sd out of bounds and ibmvfc error
handling) and the first round of esas2r checker fixes and finally the much
anticipated big endian additions for megaraid_sas.

This patch will add big endian architecture support to megaraid_sas
driver. The support added is for LSI MegaRAID all generation controllers-
(3Gb/s, 6Gb/s and 12 Gb/s controllers).
We have done basic sanity test @ppc64 arch and @x86_64. Additional
testing/observations are welcome.

MegaRAID older Firmware does not support uneven span configuration for PRL11.
E.g User wants to create 34 Driver PRL11 config, it was not possible using old
firmware, since it was not supported configuration in old firmware
Old Firmware expect even number of Drives in each span and same number of
physical drives at each span. Considering above design, 17 Drives at Span-0
and 17 drives at span-1 was not possible.
Now, using this new feature Firmware and Driver both required changes. New
Firmware can allow user to create 16 Drives at span-0 and 18 Drives at
span-1. This will allow user to create 34 Drives Uneven span PRL11.
RAID map is interface between Driver and FW to fetch all required
fields(attributes) for each Virtual Drives. Since legacy RAID map consider
Even Span design, there was no place to keep Uneven span information in
existing Raid map. Because of this limitation, for Uneven span VD, driver can
not use RAID map.
This patch address the changes required in Driver to support Uneven span PRL11
support.
1. Driver will find if Firmware has UnevenSpanSupport or not by reading
Controller Info.
2. If Firmware has UnvenSpan PRL11 support, then Driver will inform about its
capability of handling UnevenSpan PRL11 to the firmware.
3. Driver will update its copy of span info on each time Raid map update is
called.
4. Follow different IO path if it is Uneven Span. (For Uneven Span, Driver
uses Span Set info to find relavent fields for that particular Virtual
Disk)
More verbose prints will be available by setting "SPAN_DEBUG" to 1 at
compilation time.
