[PATCH 1/20] x86_64: Align data segment to PAGE_SIZE boundary

[Vivek Goyal]

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.
