perf tools: Add missing 'abi' member to 'struct regs_dump'
And store the parsed value there. Note that the 'abi' is 0 (no registers), 1 (32-bit registers) or 2 (64-bit registers), but the registers are anyway copied one-by-one as 64-bit values onto the event i.e. see 'perf_output_sample_regs()' Acked-by: Jiri Olsa <jolsa@redhat.com> Cc: David Ahern <dsahern@gmail.com> Cc: Frederic Weisbecker <fweisbec@gmail.com> Cc: Ingo Molnar <mingo@kernel.org> Cc: Jiri Olsa <jolsa@redhat.com> Cc: Mike Galbraith <efault@gmx.de> Cc: Namhyung Kim <namhyung@gmail.com> Cc: Paul Mackerras <paulus@samba.org> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Stephane Eranian <eranian@google.com> Link: http://lkml.kernel.org/r/1377591794-30553-9-git-send-email-adrian.hunter@intel.com Signed-off-by: Adrian Hunter <adrian.hunter@intel.com> Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
