From bc89663aa5c7ca620f58c34ab531ca409119becc Mon Sep 17 00:00:00 2001 From: Shawn Guo <shawn.guo@linaro.org> Date: Thu, 28 Jun 2012 14:42:08 +0800 Subject: ARM: fiq: change FIQ_START to a variable MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The commit a2be01b (ARM: only include mach/irqs.h for !SPARSE_IRQ) makes mach/irqs.h only be included for !SPARSE_IRQ build. There are a nubmer of platforms have FIQ_START defined in mach/irqs.h for FIQ support. arch/arm/mach-rpc/include/mach/irqs.h:#define FIQ_START 64 arch/arm/mach-s3c24xx/include/mach/irqs.h:#define FIQ_START IRQ_EINT0 arch/arm/plat-mxc/include/mach/irqs.h:#define FIQ_START 0 If SPARSE_IRQ is enabled for any of these platforms, the following compile error will be seen. arch/arm/kernel/fiq.c: In function ‘enable_fiq’: arch/arm/kernel/fiq.c:127:19: error: ‘FIQ_START’ undeclared (first use in this function) arch/arm/kernel/fiq.c:127:19: note: each undeclared identifier is reported only once for each function it appears in arch/arm/kernel/fiq.c: In function ‘disable_fiq’: arch/arm/kernel/fiq.c:132:20: error: ‘FIQ_START’ undeclared (first use in this function) The patch changes fiq code to have init_FIQ take FIQ_START from platforms as a parameter and assign it to variable fiq_start which is to replace FIQ_START uses in enable_fiq/disable_fiq.
