o sparc32 files with identical names to sparc64 renamed to <name>_32.S
o introduced a few Kconfig helpers to simplify Makefile logic
o refactored Makefile to prepare for unification
  - use obj-$(CONFIG_SPARC32) for sparc32 specific files
  - use <name>_$(BITS) for files where sparc64 has a _64 variant
  - sparc64 directly include a few files where sparc32 builds them,
    refer to these files directly (no BITS)
  - sneaked in -Werror as used by sparc64
o modified sparc/Makefile to use the new names for head/init_task

This patch makes the two vmlinux.lds.S files identical
and serve as documentation for the changes in each file.

This mainly add stuffs to sparc32 that is otherwise only
used by sparc64 and thus it should have no effect.

Build tested only.

All noise since we don't have CPU hotplug there.  However, they
did expose something very odd-looking in there - poke_viking()
does a bunch of identical btfixup each time it's called (i.e.
for each CPU).  That one is left alone for now; just the trivial
misannotation fixes.

This fixes a boot failure reported by Robert Reif.

The code above the section change expects to fallthrough, so
we can't make such a section change here.

Latest mainline gives this section mismatch on sparc:

The function current_pc() references
the variable __init no_sun4u_here.
This is often because current_pc lacks a __init
annotation or the annotation of no_sun4u_here is wrong.

Since current_pc() is used only in early time, it is correct to
put it in .init section.

The latest mainline gives this section mismatch on sparc:

The function __devinit apc_probe() references
a variable __initdata apc_no_idle.
If apc_no_idle is only used by apc_probe then
annotate apc_no_idle with a matching annotation.

Since the commit 7e7e2f03,
apc_probe() is on __devinit so we have to correct apc_no_idle
which is referenced by this function.

http://marc.info/?l=linux-sparc&m=103939103607617&w=2

is to add VME bus support but it's really a cleanup of the mask code.

This results in the core dumping code allocating waayyyy too
