Tried making CONFIG_EXECMEM=n (rather deselecting) but that did now allow setting CONFIG_EXECMEM=n, it always remained set. Reverting this patch i.e the current behaviour is also the same (CONFIG_EXECMEM always remains set). select ARCH_WANTS_EXECMEM_LATE if EXECMEM Above statement seems to be selecting EXECMEM as well but the intent seems to be a dependency check instead! OR arch selection for a config brings in all its dependencies as well. If the selection is always, should this change be like the following ? config ARCH_WANTS_EXECMEM_LATE bool selects EXECMEM Although a similar config ARCH_WANTS_EXECMEM_ROX is dependent on MMU and !HIGHMEM at the generic memory level.
