[PATCH] x86_64: Align data segment to PAGE_SIZE boundary
o Explicitly align data segment to PAGE_SIZE boundary otherwise depending on config options and tool chain it might be placed on a non PAGE_SIZE aligned boundary and vmlinux loaders like kexec fail when they encounter a PT_LOAD type segment which is not aligned to PAGE_SIZE boundary.
