Subject: [PATCH] x86_64: Align data segment to PAGE_SIZE boundary
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=9a14f2964b459c18198ee59ff7212321def82df7;p=linux-beck.git

[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.
