Obviously (1 << 7) being expected as invalid flag is not working well at least on ppc64le. It might be something page size related or alignment. I was looking into SYSCALL_DEFINE6(mmap, ...) implementations. Although ppc64le implementation is not the same as most of implementations on other archs, in the end it also calls ksys_mmap_pgoff(addr, len, prot, flags, fd, off >> shift) as the other archs. Any idea what could be a problem? Kind regards, Petr -- Mailing list info: https://lists.linux.it/listinfo/ltp
