Please at the very least do not leave any file half-baked, with some
symbols fixed and other not. Any file you start fixing should be
entirely fixed.
Regarding fixing other ASM files unrelated to your patch set, then no,
you don't need to fix them. Others will have to do any outstanding fixes
them when they add Thumb support for their own target.
Amicalement,
