Hi Joe, hi Ben, While reviewing some kernel config, I came across CONFIG_DCACHE_WORD_ACCESS and tried to understand its purpose. Then, I discovered this RFC patch from 2014 that seems never to have been integrated: https://lore.kernel.org/all/1393964591.20435.58.camel@joe-AO722/ [RFC] Remove CONFIG_DCACHE_WORD_ACCESS The discussion seemed to just not continue and the patch was just not integrated by anyone. In the meantime, the use of CONFIG_DCACHE_WORD_ACCESS has spread into a few more files, but replacing it with CONFIG_HAVE_EFFICIENT_UNALIGNED_ACCESS still seems feasible. Are you aware of reasons that this patch from 2014 should not be integrated? I would spend some time to move the integration of this patch further if you consider that the patch is not completely wrong. Best regards, Lukas
