[PATCH 0/3] Enable IAMR storage keys for radix

[Balbir Singh]

This series follows up on
https://lists.ozlabs.org/pipermail/linuxppc-dev/2016-August/147840.html

The first patch sets up AMOR in hypervisor mode. AMOR
needs to be setup before IAMR (details of AMOR/IAMR in
each patch). The second patch enables detection of exceptions
generated due to instruction fetch violations caused
and OOPSs' the task. The third patch enables IAMR for
both hypervisor and guest kernels.

I've tested with patch series with a sample hack and
payload.
