From 217f6710c275118af1008bb1447d244be52d2dc3 Mon Sep 17 00:00:00 2001 From: Finn Thain Date: Tue, 1 May 2007 22:32:58 +0200 Subject: m68k: Mac IRQ cleanup There are no slow IRQs on Macs since Roman Zippel's IRQ reorganisation that went into 2.6.16 and removed mac_irq_list[] and the do_mac_irq_list() dispatcher. (They were implemented in do_mac_irq_list() by lowering the IPL.) Hence there's no more use for mutual exclusion in the Mac interrupt dispatchers. Remove it.
