> When testing with rte_hash library and TSX, a higher level of transaction
> aborts was observed in some cases, especially with newer compilers.  These
> patches reduce aborts by ensuring that the compiler does not accidentally
> insert instructions that cause aborts, and by adding in delays on retry to
> avoid repeated collisions.
