[PATCH 07/11] x86: use new macro for .data.cacheline_aligned section.

[Tim Abbott]

.data.cacheline_aligned should not need a separate output section;
this change moves it into the .data section.

This removes the extra ALIGN(PAGE_SIZE) before the cache-aligned data
on x86_32, since I don't see a purpose for it.
