Doesn't seem to apply on current net-next:

    $ git am -3 16577.patch
    Applying: Replace numeric parameter like 0444 with macro
    Using index info to reconstruct a base tree...

    Patch failed at 0001 Replace numeric parameter like 0444 with macro
    The copy of the patch that failed is found in: .git/rebase-apply/patch
    When you have resolved this problem, run "git am --continue".
    If you prefer to skip this patch, run "git am --skip" instead.
    To restore the original branch and stop patching, run "git am --abort".

The code for it can now be found at net/batman-adv/bat_algo.c

Also the prefix "batman-adv: " is missing in the subject and you should
include <linux/stat.h> in net/batman-adv/bat_algo.c to make sure that these
macros are actually defined before you use them.

So you would end up with something more like:
