a613f706c3 ib_srpt: RHEL 7.1 build fix 
With the RHEL 7.0 kernel ib_register_mad_agent() takes eight
arguments. With the RHEL 7.1 kernel the same function takes nine
arguments. Detect at build time how many arguments this function
takes.

c32f79f6c1 Revert T10-PI support 
The T10-PI patch (r6162) increases the time needed to run mkfs.ext4
over iSCSI from less than a second to several minutes. This is a
regression so revert the T10-PI patch until there is sufficient time
to find the root cause of this regression and to fix this regression.

4ac6d7a26d [PATCH] scst: Drop detect() method 
There is no need for a detect() method - code that is present in such
a method can be moved to module_init(). Hence declare this method
obsolete. Leave the detect pointer member in the target template for
now for out-of-tree SCST drivers.

InfiniBand MSI-X vectors are associated with different CPU's.
