Umm. As a commit message this sucks. What's so optimized about this?

Yeah, it does. Sorry about that.
This patch sorts the sections by alignment requirements, which should pack
them essentially optimally. The old RW_DATA_SECTION had INIT_TASK_DATA
(which was more-than-PAGE_SIZE-aligned), followed by a bunch of small
alignment stuff, followed by more PAGE_SIZE-aligned stuff, so you wasted
memory in the middle of .data re-aligning back up to PAGE_SIZE.

page.h includes ifndef __ASSEMBLY__ guards, but PAGE_SIZE is defined
using "1UL", which the assembler does not support. Use the _AC macro
from const.h to make it available to assembly (and linker scripts).

Previously, m32r's asm/thread_info.h defined THREAD_SIZE differently
for assembly and C code; now that PAGE_SIZE is usable from assembly,
these can be combined. Also, m32r's asm/processor.h redefines
THREAD_SIZE to the same value; remove this redundant definition.

Previously, asm/thread_info.h was not usable from linker scripts
because it contains a piece of .macro code. Since that code was only
used in the m32r entry.S, the right fix is probably to move the macro
there.

It appears that m32r copied the .altinstructions definition from x86
when the architecture was first merged into Linux. m32r doesn't put
anything in .altinstructions, so this is just dead code.
The following block affecting .exit.text/.exit.data, which has a
comment also copied from x86, should also be deleted; the linker
script later discards the .exit.text and .exit.data sections.

Since these get squashed into the .data output section by the m32r
linker script, it seems likely that they don't need their own input
sections.
At Hirokazu Takata's suggestion, we place these structures in
.init.data rather than just placing them in .data (since they are only
used at init time).
This patch is preparation for cleaning up the m32r architecture to use
the new macros in vmlinux.lds.h; if these sections are indeed not
needed, then we can use the RW_DATA_SECTION macro for m32r and save a
bunch of redundant code.

This patch is largely a straightforward conversion. One thing to note
is that the new macros use fewer separate output sections than the old
code; this should have no functional impact but is relevant for people
objdumping vmlinux files.
Also note that it moves the .data.init_task output sections inside
_edata.

This patch has the (likely harmless) side effect of moving
.data.init_task inside the _edata.
It also changes the alignment of .data.init_task from 16384 to
THREAD_SIZE, which can in some configurations be larger than 16384. I
believe that this change fixes a potential bug on those
configurations.

Heh, I had a patch to use this, but I guess I never finished it, (to nop
out some cache flushes and syncs on coherent architectures in the iommu
code.) I'll add a hunk to bring it back if/when I ever submit that
change.
cheers, Kyle
