Michael Neuling 82a9f16adc powerpc/hw_breakpoints: Add DABRX cpu feature to fix 32-bit regression ... When introducing support for DABRX in 4474ef0, we broke older 32-bit CPUs that don't have that register. Some CPUs have a DABR but not DABRX. Configuration are: - No 32bit CPUs have DABRX but some have DABR. - POWER4+ and below have the DABR but no DABRX. - 970 and POWER5 and above have DABR and DABRX. - POWER8 has DAWR, hence no DABRX. This introduces CPU_FTR_DABRX and sets it on appropriate CPUs. We use the top 64 bits for CPU FTR bits since only 64 bit CPUs have this. Processors that don't have the DABRX will still work as they will fall back to software filtering these breakpoints via perf_exclude_event().
