[PATCH v2 00/15] clean up page aligned data and bss sections

[Tim Abbott]

Sam,

Here's a new version of the page-aligned section cleanup patch
series.  Changes since last version include:

- added missing semicolons for ALIGN() directives in the macro
  definitions in PATCH 1/14.
- fixed a bug in the powerpc patch where the DATA_PAGE_ALIGNED was
  inside a CONFIG_PPC32 in PATCH 11/14 (which is now 2 patches)

---

This patch series add new macros for .data.page_aligned and
.bss.page_aligned, and converts the various architectures to use them.
It also eliminates the few remaining uses of .data.idt by replacing
them with references to .data.page_aligned.

This patch series is a bunch of cleanup in preparation for being able
to change the names of the .data.page_aligned and .bss.page_aligned
sections to be compatabible with -ffunction-sections -fdata-sections.

The x86 patches are on top of the your commit in the x86/kbuild of
linux-tip entitled:

    x86: beautify vmlinux_64.lds.S

as requested by Linus.
