The "leave kernel" paths on ia64 are a bit tortuous ... clearly there is some point at which the kernel needs to lock out interrupts and just get on with returning to the user. We don't want to allow races after we check the TIF* bits where interrupts could result in more signals pending for the process. Perhaps we can re-order things to satisfy all the interrupts enabled vs. interrupts disabled requirements. -Tony -- To unsubscribe from this list: send the line "unsubscribe linux-ia64" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
