They are non-exported variables; therefore they are always empty whenever descending into each subdirectory. (Moreorver, obj-y and obj-m are also set to empty at the beginning of scripts/Makefile.build) Signed-off-by: Masahiro Yamada <yamada.m@...panasonic.com> --- arch/arm/mach-at91/Makefile | 3 --- arch/arm/mach-ebsa110/Makefile | 3 --- arch/arm/mach-ep93xx/Makefile | 3 --- arch/arm/mach-exynos/Makefile | 5 ----- arch/arm/mach-footbridge/Makefile | 3 --- arch/arm/mach-iop13xx/Makefile | 5 ----- arch/arm/mach-iop32x/Makefile | 3 --- arch/arm/mach-iop33x/Makefile | 3 --- arch/arm/mach-ks8695/Makefile | 3 --- arch/arm/mach-rpc/Makefile | 4 ---- arch/arm/mach-s3c24xx/Makefile | 5 ----- arch/arm/mach-s3c64xx/Makefile | 5 ----- arch/arm/mach-s5pv210/Makefile | 5 ----- arch/arm/mach-sa1100/Makefile | 3 --- arch/arm/mach-u300/Makefile | 3 --- arch/arm/plat-iop/Makefile | 6 ------ arch/arm/plat-omap/Makefile | 3 --- arch/arm/plat-samsung/Makefile | 4 ---- 18 files changed, 69 deletions(-) diff --git a/arch/arm/mach-at91/Makefile b/arch/arm/mach-at91/Makefile index 78e9cec..75033839 100644 --- a/arch/arm/mach-at91/Makefile +++ b/arch/arm/mach-at91/Makefile @@ -3,9 +3,6 @@ # obj-y := irq.o gpio.o setup.o sysirq_mask.o -obj-m := -obj-n := -obj- := obj-$(CONFIG_OLD_CLK_AT91) += clock.o obj-$(CONFIG_AT91_SAM9_ALT_RESET) += at91sam9_alt_reset.o diff --git a/arch/arm/mach-ebsa110/Makefile b/arch/arm/mach-ebsa110/Makefile index 935e4af..a7d68c1 100644 --- a/arch/arm/mach-ebsa110/Makefile +++ b/arch/arm/mach-ebsa110/Makefile @@ -5,6 +5,3 @@ # Object file lists. obj-y := core.o io.o leds.o -obj-m := -obj-n := -obj- := diff --git a/arch/arm/mach-ep93xx/Makefile b/arch/arm/mach-ep93xx/Makefile index 0dc51f9..78d427b 100644 --- a/arch/arm/mach-ep93xx/Makefile +++ b/arch/arm/mach-ep93xx/Makefile @@ -2,9 +2,6 @@ # Makefile for the linux kernel. # obj-y := core.o clock.o -obj-m := -obj-n := -obj- := obj-$(CONFIG_EP93XX_DMA) += dma.o diff --git a/arch/arm/mach-exynos/Makefile b/arch/arm/mach-exynos/Makefile index 788f26d..27ae614 100644 --- a/arch/arm/mach-exynos/Makefile +++ b/arch/arm/mach-exynos/Makefile @@ -7,11 +7,6 @@ ccflags-$(CONFIG_ARCH_MULTIPLATFORM) += -I$(srctree)/$(src)/include -I$(srctree)/arch/arm/plat-samsung/include -obj-y := -obj-m := -obj-n := -obj- := -
