Has anyone already looked into TIF_NOTIFY_RESUME support for m68k?
You need to change your entry.S code where it now does single-bit tests for TIF_SIGPENDING with lsl/jmi do_signal_return, to instead test a 2-bit (or larger, it that gives better code) flag field for zero/non-zero. TIF_SIGPENDING and TIF_NOTIFY_RESUME should be alone in that field. In the non-zero case you should call a new do_notify_resume() written in C, which will then test TIF_SIGPENDING and TIF_NOTIFY_RESUME just like many other archs do. BTW, m68k also lacks TIF_RESTORE_SIGMASK support. You could probably use the one I added to ARM very recently as a model. Do current 2.6.3x m68k kernels boot on aranym? Last time I tried aranym it could only boot som ancient hacked 2.4 kernel, for 2.6 kernels I got disk detection errors due to what looked like byteswapping issues. -- To unsubscribe from this list: send the line "unsubscribe linux-m68k" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
