Backport 3 patches to fix bugs with AIX clients using IBMVSCSI Target
Driver
Status in linux package in Ubuntu:
New
Bug description:
== Comment: #0 - BRYANT G. LY - 2017-01-16 10:35:29 ==
---Problem Description---
Ibmvscsi Target driver isn't working properly due to a bug where we are
sleeping in an interrupt context, also the max transfer length is incorrectly
assuming 4k page tables instead of 64k for ppc64.
---Steps to Reproduce---
Use TCMU-Runner with AIX clients

Need three of these patches back ported to 4.4 kernel / 4.8 kernel. It
has all been queued up for 4.10 kernel under target-devel subsystem.
