Subject: [PATCH] x86: update vmlinux.lds.S to place .data section on a page boundary

Patch to update vmlinux linker script so that .data section is on a page
boundary.  without this change the kernel's .data section is on a non-4k
boundary, and this prevents kexec from loading a new kernel.  Tested
successfully by me.

Thanks & Regards
Neil
