A commit message describing some of the change details and a note it uses
the for-each cpu copies (same as normal syscall on percpu map) and not the
per-cpu ones would be nice. I at least had to go and check the generic_map*
batch operations.

Also something about why generic_map_delete_batch is omitted?
