Hi Thomas,
Could you please also merge this patch? Since you have merged this patch
"x86, boot: Skip relocs when load address unchanged [commit f285f4a21]",
and this issue was raised because it broke kexec/kdump, then I posted
these 2 patches. Without this patch makedumpfile will be broken when
enable kaslr and do the kdump.
Thanks
Baouqan
