I have to confess that it took me while to wrap around my head
with the new min() change, but looks ok:

It's a pattern commonly used in compilers and emulators to calculate the
number of bytes to the next block/alignment. (we're missing a macro
(like we have ALIGN_UP/IS_ALIGNED) for that - but it's hard to come up
with a good name (e.g., SIZE_TO_NEXT_ALIGN) .

You can just write the easy to understand

  ...  ALIGN_UP(x) - x  ...

which is better *without* having a separate name.  Does that not
generate good machine code for you?
