Subject: [PATCH v1 0/1] perf: High-order AUX allocations

Hi Peter,

This supersedes [1]. Since there is no reason not to always go with high
order allocations, we simply change the AUX allocator to optimistically
do that with a fallback to lower orders. And since this is not an opt-in
any more, no tool changes.

  perf: Optimistically use high order allocations for AUX buffers
