Re: [PATCH V3 0/2] selftests/powerpc: Updates to EBB selftest for ISA v3.1

The "no_handler_test" in ebb selftests attempts to read the PMU
registers after closing of the event via helper function
"dump_ebb_state". With the MMCR0 control bit (PMCCEXT) in ISA v3.1,
read access to group B registers is restricted when MMCR0 PMCC=0b00.
Hence the call to dump_ebb_state after closing of event will generate
a SIGILL, which is expected.

Applied to powerpc/next.
