ARM: decompressor: Include .data.rel.ro.local
The .data.rel.ro.local section has the same semantics as .data.rel.ro here, so include it in the .rodata section of the decompressor. Additionally since the .printk_index section isn't usable outside of the core kernel, discard it in the decompressor. Avoids these warnings: arm-linux-gnueabi-ld: warning: orphan section `.data.rel.ro.local' from `arch/arm/boot/compressed/fdt_rw.o' being placed in section `.data.rel.ro.local' arm-linux-gnueabi-ld: warning: orphan section `.printk_index' from `arch/arm/boot/compressed/fdt_rw.o' being placed in section `.printk_index' Reported-by: kernel test robot <lkp@intel.com> Link: https://lore.kernel.org/linux-mm/202209080545.qMIVj7YM-lkp@intel.com Cc: Russell King <linux@armlinux.org.uk> Cc: linux-arm-kernel@lists.infradead.org Signed-off-by: Kees Cook <keescook@chromium.org>
