 * SAVE_MOST/RESTORE_MOST is used for the faster version of IRQ handlers,
 * installed by using the SA_INTERRUPT flag. These kinds of IRQ's don't
 * call the routines that do signal handling etc on return, and can have
 * more relaxed register-saving etc. They are also atomic, and are thus
 * suited for small, fast interrupts like the serial lines or the harddisk
 * drivers, which don't actually need signal handling etc.
 *
 * Also note that we actually save only those registers that are used in
 * C subroutines, so if you do something weird, you're on your own.
