Eric W. Biederman 2dab221939 mn10300/misalignment: Use SIGSEGV SEGV_MAPERR to report a failed user copy ... commit 6ac1dc736b upstream. Setting si_code to 0 is the same a setting si_code to SI_USER which is definitely not correct. With si_code set to SI_USER si_pid and si_uid will be copied to userspace instead of si_addr. Which is very wrong. So fix this by using a sensible si_code (SEGV_MAPERR) for this failure.
