Subject[PATCH] x86_64: Align data segment to PAGE_SIZE boundary
Hi Andi,

This patch was previously part of relocatable kernel series but now I have
forked it out as it is required for 2.6.19 kernels and relocatable kernel
patches have to wait.

Please apply.

Thanks
Vivek


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.
