[PATCH 1/3] powerpc/64s: fix handling of non-synchronous machine checks

2017-02-27 Thread Nicholas Piggin
A synchronous machine check is an exception raised by the attempt to execute the current instruction. If the error can't be corrected, it can make sense to SIGBUS the currently running process. In other cases, the error condition is not related to the current instruction, so killing the current
