Thanks Peter for the suggestions, I also added a patch to switch a 
couple of cpu_restore_state+raise_exception pairs in stack limit 
exception handling for both v7m and v8m.

v2:
 - fix raise_exception_ra to restore state before raising exception
 - remove redundant do_raise_exception
 - remove now redundant open coded raise_exception_ra from MTE and stack 
   limit exception handling

Jamie Iles (4):
  target/arm: fix missing exception class
  target/arm: fold do_raise_exception into raise_exception
  target/arm: use raise_exception_ra for MTE check failure
  target/arm: use raise_exception_ra for stack limit exception

Applied to target-arm.next, thanks. (I tweaked a couple of comments
and commit messages.)
