. an instruction fetch pagefault generates a prefetch abort exception, this should also be a source of a pagefault event . the saved_lr argument to the C exception handler was sometimes an address, sometimes a pointer to that address; the kernel sometimes dereferences it, so it should always be an in-kernel address, never a userspace address. fix in mpx.S makes it always a pointer. . move dumping of all processes over serial out of the arch-specific arch_system.c
