From 060fd1be0c720166091470ffb7846512b82c1a87 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Thu, 14 Feb 2013 13:50:57 +0100 Subject: [PATCH] ARM: integrator/versatile: fix NOMMU warnings On NOMMU kernels, the io_desc variables are unused because we don't use the MMU to remap the MMIO areas. Marking these variables as __maybe_unused easily avoids the otherwise harmless warnings like warning: 'versatile_io_desc' defined but not used Signed-off-by: Arnd Bergmann Cc: Linus Walleij Cc: Russell King --- arch/arm/mach-integrator/integrator_ap.c | 2 +- arch/arm/mach-integrator/integrator_cp.c | 2 +- arch/arm/mach-versatile/core.c | 2 +- 3 files changed, 3 insertions(+), 3 deletions(-) diff --git a/arch/arm/mach-integrator/integrator_ap.c b/arch/arm/mach-integrator/integrator_ap.c index 11e2a4145807..11b1d21f3c77 100644 --- a/arch/arm/mach-integrator/integrator_ap.c +++ b/arch/arm/mach-integrator/integrator_ap.c @@ -94,7 +94,7 @@ void __iomem *ap_syscon_base; * f1b00000 1b000000 GPIO */ -static struct map_desc ap_io_desc[] __initdata = { +static struct map_desc ap_io_desc[] __initdata __maybe_unused = { { .virtual = IO_ADDRESS(INTEGRATOR_HDR_BASE), .pfn = __phys_to_pfn(INTEGRATOR_HDR_BASE), diff --git a/arch/arm/mach-integrator/integrator_cp.c b/arch/arm/mach-integrator/integrator_cp.c index 7322838c0447..01a888d7b0b8 100644 --- a/arch/arm/mach-integrator/integrator_cp.c +++ b/arch/arm/mach-integrator/integrator_cp.c @@ -78,7 +78,7 @@ static void __iomem *intcp_con_base; * fcb00000 cb000000 CP system control */ -static struct map_desc intcp_io_desc[] __initdata = { +static struct map_desc intcp_io_desc[] __initdata __maybe_unused = { { .virtual = IO_ADDRESS(INTEGRATOR_HDR_BASE), .pfn = __phys_to_pfn(INTEGRATOR_HDR_BASE), diff --git a/arch/arm/mach-versatile/core.c b/arch/arm/mach-versatile/core.c index 5d5929450366..60c092cfdae3 100644 --- a/arch/arm/mach-versatile/core.c +++ b/arch/arm/mach-versatile/core.c @@ -114,7 +114,7 @@ void __init versatile_init_irq(void) writel(PIC_MASK, VA_SIC_BASE + SIC_INT_PIC_ENABLE); } -static struct map_desc versatile_io_desc[] __initdata = { +static struct map_desc versatile_io_desc[] __initdata __maybe_unused = { { .virtual = IO_ADDRESS(VERSATILE_SYS_BASE), .pfn = __phys_to_pfn(VERSATILE_SYS_BASE),
