Heiko Carstens 5f4787834c s390/entry: Fix last breaking event handling in case of stack corruption ... commit ae952eea6f upstream. In case of stack corruption stack_invalid() is called and the expectation is that register r10 contains the last breaking event address. This dependency is quite subtle and broke a couple of years ago without that anybody noticed. Fix this by getting rid of the dependency and read the last breaking event address from lowcore.
