Ram Pai submitted a separate series containing the rework of the x86 test and also the powerpc-specific tests:
https://patchwork.ozlabs.org/project/linuxppc-dev/list/?series=24741
There's a bug in the powerpc tests where they expect the AMR, IAMR and UAMOR registers to be zeroed when a process starts. This is currently true on powernv but isn't on LPARs, where key 31 is reserved and its bits are set. This causes the tests to fail on that platform.
This series fixes the bug and now the tests pass on both powernv and LPAR machines running powerpc/next. I think it's worth submitting these tests separately from the one coming from x86 so here they are.
