This is not functionally equivalent. Are you sure the entire if else
chain still behaves correctly?

Same story as above.

This turns integer conversions into floating point conversions. I don't
this floating point operations are allowed in the kernel.

Your patch does too many things at once. Please try to break it into
smallers patches that only do one (logical) change.
