Hi, i'm new to the list (my first kernel mailing list). I'd like to request to add a way to distinguish a read from a write pagefault in userspace on arm64(aarch64). (That's e.g. in a SIGSEGV handler attached with sigaction and SA_SIGINFO) On arm you can use the bit at 0x800 in uc_mcontext.error_code to know which kind it is, but on arm64 i can't find a way. (On most other popular architectures you can get that information, too) I'd suggest to add a flag to siginfo.si_errno, or to make the esr available to the SIGSEGV handler. Any hints or suggestions? -- Best Regards, André Hentschel -- To unsubscribe from this list: send the line "unsubscribe linux-arch" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
