This is look alright to me now, but there are still two blockers: (1) Getting the libunwind code merged (2) Splitting this into an arch/arm64 series and a tools/perf series, so that acme can merge the latter independently (and avoid the mess we had last time). Anyway, for the series: Acked-by: Will Deacon Will
