Subject: [PATCH v1 0/3] Generic weight struct, use env for sort key and header

The arch directory is a barrier to cross-platform development as files
and behaviors within it are inherently platform specific. Sample
parsing should be generic but the PERF_SAMPLE_WEIGHT_STRUCT handling
was only present if building for x86 or powerpc. The sort key and
headers should be specific to the session that is being executed and
not to the machine perf is being run upon. These patches clean this
and associated code up.

Ian Rogers (3):
  perf sample: Remove arch notion of sample parsing
  perf test: Move PERF_SAMPLE_WEIGHT_STRUCT parsing to common test
  perf sort: Use perf_env to set arch sort keys and header
