I've taken this new iteration again through modules-next so to help get
more testing exposure to this. If we run into conflicts again with mm
we can see if Andrew is willing to take this in through there. However,
it may make sense to only consider up to "mm: introduce execmem_alloc() and
execmem_free()" for v6.10 given we're bound to likely find more issues
and we are already at rc5.
