[RFC] arm: add __initbss section attribute

This attribute can make init data to be into .initbss section, this will make the data to be NO_BITS in vmlinux, can shrink the Image file size, and speed up the boot up time. Signed-off-by: yalin wang --- arch/arm/kernel/vmlinux.lds.S | 2 +- arch/arm/mm/init.c| 1 +
