the code in question comes from the compare_and_swap implementation for
arm implemented in assembler in config/arm/atomicity.h . That code comes
from GNU C library, and has been slightly tweaked.

Your mission would be to implement (or find a GPL compatible
implementation of to include) compare_and_swap in a way that works for
your assembler. Alternatively, there is a generic (but slow) compare and
swap implementation in config/generic that you could tweak the code to use.
