Subject: [ofw][patch][ibal] use non-pageable memory to prevent
possibleproblems on power down
IBAL uses pageable memory to create PnP context.
It can create possible problems in power down flows at the time
of system contention.
We saw some similar case at a customer.
There is no strong evidence that that is what influenced, but
with this patch IBAL will be more safe and at no cost.
Found by Hobin Lee (Xsigo).
