What would it take for this patch (with only generic type changes) to be
applied?

I did some further investigations and disassembled my test kernel images.
The patch reduced the number of ARM instructions by 872 with GCC 13 and by
2,354 with GCC 14. Other architectures that rely on the generic bitops
functions will most likely also benefit from this patch.

Tests were done with base commit 9d1ddab261f3e2af7c384dc02238784ce0cf9f98.

Thanks,
Thorsten
