From f26fdd59929e1144c6caf72adcaf4561d6e682a4 Mon Sep 17 00:00:00 2001 From: Karsten Wiese Date: Tue, 6 Sep 2005 15:17:25 -0700 Subject: [PATCH] CHECK_IRQ_PER_CPU() to avoid dead code in __do_IRQ() IRQ_PER_CPU is not used by all architectures. This patch introduces the macros ARCH_HAS_IRQ_PER_CPU and CHECK_IRQ_PER_CPU() to avoid the generation of dead code in __do_IRQ(). ARCH_HAS_IRQ_PER_CPU is defined by architectures using IRQ_PER_CPU in their include/asm_ARCH/irq.h file. Through grepping the tree I found the following architectures currently use IRQ_PER_CPU: cris, ia64, ppc, ppc64 and parisc.
