   Please note that one significant impact of this is an increase of the stack size.  This moves all the coprocessors saving area to the stack not just the FPU.  For SoCs where they have more than just one coprocessor, like the ESP32-S3, users will need to be careful when selecting their stack sizes.
   
   I have more or less the same change, although for me I moved the saving area to the beginning of the stack and not in the interrupt frame, this is to experiment with lazy context switching.
