Hi Paul,

That is a fair point, and I completely agree with your philosophy.

I will decouple them accordingly. I will submit the MIPS FPU affinity fix
as a standalone patch first so it can be routed, reviewed, and potentially
backported independently.

Once that is out, I will submit the LSM hook modification and the rest of
this feature series separately, rebased on top of the MIPS fix, and will
include a clear note regarding the dependency.

Thanks for the guidance.


Kind regards,
