Hi Bryant,
A few things:
1) The commit message could probably be trimmed, especially the stack
traces.
2) What exactly are you changing and why does it fix the issue? I
couldn't figure that out from the commit message.
3) Does this need a Fixes: tag?

The following script when run (along with some iperf traffic recreates the
crash within 5-10 mins or so).
while true
do
ethtool -k ibmveth0 | grep tcp-segmentation-offload
ethtool -K ibmveth0 tso off
ethtool -k ibmveth0 | grep tcp-segmentation-offload
ethtool -K ibm
This patch implements and enables VDP support for the ibmvnic driver.
Moreover, it includes the implementation of suitable structs, signal
transmission/handling and functions which allows the retrival of firmware
information from the ibmvnic card through the ethtool command.

Match powerpc/64 and include .data.rel* input sections in the .data output
section explicitly.
This solves the warning:
powerpc-linux-gnu-ld: warning: orphan section `.data.rel.ro' from
`arch/powerpc/kernel/head_44x.o' being placed in section `.data.rel.ro'.

While reviewing the code I found that the flush assumes all
pages are of mmu_linear_psize, which is not correct. The patch
uses find_linux_pte to find the right page size and uses that
for launching the ATSD invalidation. A new helper is added
to abstract the invalidation from the various notifiers
