Hello, Linus,
The following is a series of patches to update m32r architecure support
for 2.6.23-rc5:
- Rearrange platform support codes and move them to arch/m32r/platforms/
- Move config files to arch/m32r/config/
- Simplify and cleanup ei_handler routine of arch/m32r/kernel/entry.S
Please pull from the "for-linus" branch of
git://www.linux-m32r.org/git/takata/linux-2.6_dev.git
Thease patches have tested after 2.6.23-rc3-mm1.
Thanks,
-- Takata

m32r: Rename STI/CLI macros
The names of STI and CLI macros were derived from i386 arch historically,
but their name are incomprehensible.
So, for easy to understand, rename these macros to ENABLE_INTERRUPTS
and DISABLE_INTERRUPTS, respectively.

m32r: Exit ei_handler directly for no IRQ case or IPI operations
If no IRQ request is found in the IRQ check of ei_handler,
we can exit directly by jumping "restore_all", instead of via
"ret_from_intr".
This modification is also likely effective for IPI operations,
because scheduler call never happen at the exit of IPIs.

m32r: Simplify ei_handler code
Simplify and clean up messy ei_handler code in arch/m32r/kernel/entry.S.
- Remove ifdef's for CONFIG_CHIP_* configulations.
- Rearrange the M32700 workaround code.
- Remove the messy platform-dependent interrupt check routines and
consolidate them to common INT0/INT1/INT2 check routines for all
platforms with cascaded interrupt controllers.

m32r: Define symbols to unify platform-dependent ICU checks
On some m32r platforms, cascaded ICUs are used.
This patch is required to simplify ei_handler and consolidate platform-
dependent ICU check routines.

m32r: Move defconfig files to arch/m32r/configs/
Change defconfig file's location from arch/m32r/{platform}/defconfig*
to arch/m32r/configs/{platform}_defconfig.
Applying this patch, we can use defconfig file for each m32r platform
easily, like other architectures.
ex. Setup defconfig for cross-building
$ make ARCH=m32r CROSS_COMPILE=m32r-linux-gnu- {platform}_defconfig.
