Subject: [PATCH 1/2] fix a Section mismatch in arch/x86/kernel/setup.c

[Helight.Xu]

copy_edd() should be __init.
warning msg:
WARNING: vmlinux.o(.text+0x7759): Section mismatch in reference from the 
function copy_edd() to the variable .init.data:boot_params
The function copy_edd() references
the variable __initdata boot_params.
This is often because copy_edd lacks a __initdata
annotation or the annotation of boot_params is wrong.
