Yeah please do.

Seeing this patch in isolation, with no change log, I might think it's
safe for me to just apply it.

But that would break the build because I don't have patch 1.

So for starters you need to explain that part, eg something like:

  A previous patch in the series added a weak definition of
  free_initrd_mem() in init/initramfs.c.

  The powerpc implementation is identical, so it can be removed allowing
  the generic version to be used.

Then you could also tell me if you did/didn't build/boot test it.

cheers
