It needs this: diff --git a/arch/arm/mach-realview/realview_eb.c b/arch/arm/mach-realview/realview_eb.c index 4d29535abeba..1a2a89708fb7 100644 --- a/arch/arm/mach-realview/realview_eb.c +++ b/arch/arm/mach-realview/realview_eb.c @@ -38,6 +38,7 @@ #include <asm/hardware/cache-l2x0.h> #include <asm/smp_twd.h> #include <asm/system_info.h> +#include <asm/outercache.h> #include <asm/mach/arch.h> #include <asm/mach/map.h> diff --git a/arch/arm/mach-realview/realview_pb11mp.c b/arch/arm/mach-realview/realview_pb11mp.c index f9817bb5d8fa..5bb460300b6a 100644 --- a/arch/arm/mach-realview/realview_pb11mp.c +++ b/arch/arm/mach-realview/realview_pb11mp.c @@ -42,6 +42,7 @@ #include <asm/mach/flash.h> #include <asm/mach/map.h> #include <asm/mach/time.h> +#include <asm/outercache.h> #include <mach/board-pb11mp.h> #include <mach/irqs.h> I've fixed it up in my tree, but I don't know yet if I'm getting anywhere with this as my PB11MPCore refuse to boot with these patches.
