Can you explain why you want this? I'm wondering about the value of saving the registers; normally when a panic occurs, it's because of a well defined reason, and not because something went wrong in some CPU register; to put it another way, a panic() is a more controlled exception than a BUG() or a bad pointer dereference. -- Russell King Linux kernel 2.6 ARM Linux - http://www.arm.linux.org.uk/ maintainer of: -- 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
