ia64: move ia64_done_with_exception out of asm/uaccess.h Move ia64_done_with_exception out of asm/uaccess.h (which is widely used) and into asm/exception.h (like ARM has) and then ensure the few callers of it include this new header. Most of the other C content in asm files is implemented in macro form. So we do that conversion at the same time as the move. There are two C exception prototypes that move along with the macro. One of them will become redundant when we switch over to using the <linux/extable.h> instead of <linux/module.h> header in a subsequent commit. Also relocate a couple of the automated asm --> linux uaccess conversions to preserve the linux and asm independent grouping, since we are in the file at that location anyway.
