Possible fix for trap concurent with xret. Fixes the priority so trap has higher priority than either sret or mret. Previous code had priority to xret in the trap logic and privilege logic, but not the csrsr logic. This caused partial execution of the instruction.

Just needed to recompile - all good. Now removed uretM because N-mode is depricated

Oups. My hack for DivE interrupt prevention was wrong.

Hack "fix" to prevent interrupt from occuring during an integer divide.
This is not the desired solution but will allow continued debuging of linux.
