mm/madvise: pass return code of memory_failure() to userspace Currently the return value of memory_failure() is not passed to userspace when madvise(MADV_HWPOISON) is used. This is inconvenient for test programs that want to know the result of error handling. So let's return it to the caller as we already do in the MADV_SOFT_OFFLINE case.
