From e77c232cfc6e1250b2916a7c69225d6634d05a49 Mon Sep 17 00:00:00 2001 From: Franck Bui-Huu Date: Fri, 1 Dec 2006 18:22:27 +0100 Subject: [MIPS] Compile __do_IRQ() when really needed __do_IRQ() is needed only by irq handlers that can't use default handlers defined in kernel/irq/chip.c. For others platforms there's no need to compile this function since it won't be used. For those platforms this patch defines GENERIC_HARDIRQS_NO__DO_IRQ symbol which is used exactly for this purpose. Futhermore for platforms which do not use __do_IRQ(), end() method which is part of the 'irq_chip' structure is not used. This patch simply removes this method in this case.
