On the ARM +kernel build, because there is no explicit mention of this section +in the shipped ld script, this section is placed at vaddr 0x00000000 +(whereas the normal kernel text/data typically starts at vaddr +0xc0008000), causing the output of objcopy (Image) to produce a 3G+ +file. + +This patch makes objcopy strip the .note.gnu.build-id section from +the Image file along with all other note sections, which fixes the +build. + +Signed-off-by: Lennert Buytenhek +Signed-off-by: Russell King +--- + +diff --git a/arch/arm/Makefile b/arch/arm/Makefile +index fa4ea9f..6c2d539 100644 +--- a/arch/arm/Makefile ++++ b/arch/arm/Makefile +@@ -12,7 +12,7 @@ + + LDFLAGS_vmlinux :=-p --no-undefined -X + CPPFLAGS_vmlinux.lds = -DTEXT_OFFSET=$(TEXT_OFFSET) +-OBJCOPYFLAGS :=-O binary -R .note -R .comment -S ++OBJCOPYFLAGS :=-O binary -R .note -R .note.gnu.build-id -R .comment -S + GZFLAGS :=-9 + #CFLAGS +=-pipe + # Explicitly specifiy 32-bit ARM ISA since toolchain default can be -mthumb:
