The current include/asm-m32r/div64.h of 2.6.12-rc5 looks buggy. Here is a
patch for updating it to use asm-generic/div64.h for m32r like other
architectures.

This patch removes an obsolete header file include/asm-m32r/m32102peri.h.
In this header, there are some undesirable single character types, like V.
And the header is almost no longer used.

This patchset is for supporting a new m32r platform, M3A-2170(Mappi-III)
evaluation board. An M32R chip multiprocessor is equipped on the board.
http://http://www.linux-m32r.org/eng/platform/platform.html
* arch/m32r/Kconfig: Support Mappi-III platform.
* arch/m32r/kernel/Makefile: ditto.
* arch/m32r/kernel/io_mappi3.c: ditto.
* arch/m32r/kernel/setup.c: ditto.
* arch/m32r/kernel/setup_mappi3.c: ditto.
* include/asm-m32r/m32102.h: ditto.
* include/asm-m32r/m32r.h: ditto.
* include/asm-m32r/mappi3/mappi3_pld.h: ditto.
* include/asm-m32r/ide.h: CF support for Mappi-III.
* arch/m32r/kernel/setup_mappi3.c: ditto.
* arch/m32r/mappi3/defconfig.smp: A default config file for Mappi-III.
* arch/m32r/mappi3/dot.gdbinit: A default .gdbinit file for Mappi-III.
* arch/m32r/boot/compressed/m32r_sio.c: Modified for Mappi-III
- At boot time, m32r-g00ff bootloader makes MMU off for Mappi-III,
on the contrary it makes MMU on for Mappi-II.
* arch/m32r/kernel/io_mappi2.c: Update comments.
* arch/m32r/kernel/setup_mappi2.c: ditto.

This patch implements a number of smp_processor_id() cleanup ideas that
Arjan van de Ven and I came up with.
The previous __smp_processor_id/_smp_processor_id/smp_processor_id API
spaghetti was hard to follow both on the implementational and on the
usage side.
Some of the complexity arose from picking wrong names, some of the
complexity comes from the fact that not all architectures defined
__smp_processor_id.
In the new code, there are two externally visible symbols:
- smp_processor_id(): debug variant.
- raw_smp_processor_id(): nondebug variant. Replaces all existing
uses of _smp_processor_id() and __smp_processor_id(). Defined
by every SMP architecture in include/asm-*/smp.h.
There is one new internal symbol, dependent on DEBUG_PREEMPT:
- debug_smp_processor_id(): internal debug variant, mapped to
smp_processor_id().
Also, i moved debug_smp_processor_id() from lib/kernel_lock.c into a new
lib/smp_processor_id.c file. All related comments got updated and/or
clarified.
I have build/boot tested the following 8 .config combinations on x86:
{SMP,UP} x {PREEMPT,!PREEMPT} x {DEBUG_PREEMPT,!DEBUG_PREEMPT}
I have also build/boot tested x64 on UP/PREEMPT/DEBUG_PREEMPT. (Other
architectures are untested, but should work just fine.)

New file - asm-generic/signal.h. Contains declarations of
__sighandler_t, __sigrestore_t, SIG_DFL, SIG_IGN, SIG_ERR and default
definitions of SIG_BLOCK, SIG_UNBLOCK and SIG_SETMASK.
asm-*/signal.h switched to including it. The only exception is
asm-parisc/signal.h that wants its own declaration of __sighandler_t;
that one is left as-is.
asm-ppc64/signal.h required one more thing - unlike everybody else it
used __sigrestorer_t instead of usual __sigrestore_t. PPC64 switched to
common spelling.

The attached patch moves the IRQ-related SA_xxx flags (namely, SA_PROBE,
SA_SAMPLE_RANDOM and SA_SHIRQ) from all the arch-specific headers to
linux/signal.h. This looks like a left-over after the irq-handling code
was consolidated. The code was moved to kernel/irq/*, but the flags are
still left per-arch.
Right now, adding a new IRQ flag to the arch-specific header, like this
patch does:
http://cvs.sourceforge.net/viewcvs.py/*checkout*/alsa/alsa-driver/utils/patches/pcsp-kernel-2.6.10-03.diff?rev=1.1
no longer works, it breaks the compilation for all other arches, unless you
add that flag to all the other arch-specific headers too. So I think such
a clean-up makes sense.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
