Convert all the parisc driver interrupt handlers (dino, eisa, gsc, iosapic and superio) as well as the cpu interrupts. Prepare show_interrupts for GENERIC_HARDIRQS_NO_DEPRECATED and finally selects that Kconfig option [jejb: compile and testing fixes] Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Signed-off-by: James Bottomley <James.Bottomley@suse.de>
