- Support bzip2 and lzma kernel compression for m32r.
- Clean up arch/m32r/boot/compressed/misc.c.

Replace the use of CROSS_COMPILE to select a customized
installkernel script with the possibility to set INSTALLKERNEL
to select a custom installkernel script when running make:
make INSTALLKERNEL=arm-installkernel install
With this patch we are now more consistent across
different architectures - they did not all support use
of CROSS_COMPILE.
The use of CROSS_COMPILE was a hack as this really belongs
to gcc/binutils and the installkernel script does not change
just because we change toolchain.
The use of CROSS_COMPILE caused troubles with an upcoming patch
that saves CROSS_COMPILE when a kernel is built - it would no
longer be installable.
[Thanks to Peter Z. for this hint]
This patch undos what Ian did in commit:
0f8e2d62fa
("use ${CROSS_COMPILE}installkernel in arch/*/boot/install.sh")
The patch has been lightly tested on x86 only - but all changes
looks obvious.

This patch fixes the following build error of 2.6.30-rc3-git2:
AS arch/m32r/kernel/head.o
In file included from /include/linux/init.h:7,
from /arch/m32r/kernel/head.S:11:
/include/linux/stringify.h:9: error: syntax error in macro parameter list
/include/linux/stringify.h:10: error: syntax error in macro parameter list
This build error was caused at __HEAD macro in arch/m32r/kernel/head.S,
which uses __stringify() macro.
Remove -traditional option from EXTRA_AFLAGS for the m32r,
because the __stringify() macro depends on the gcc's variadic macro
extension function, due to commit:
Make __stringify support variable argument macros too

Inflate requires some dynamic memory allocation very early in the boot
process and this is provided with a set of four functions:
malloc/free/gzip_mark/gzip_release.
The old inflate code used a mark/release strategy rather than implement
free. This new version instead keeps a count on the number of outstanding
allocations and when it hits zero, it resets the malloc arena.
This allows removing all the mark and release implementations and unifying
all the malloc/free implementations.
The architecture-dependent code must define two addresses:
- free_mem_ptr, the address of the beginning of the area in which
allocations should be made
- free_mem_end_ptr, the address of the end of the area in which
allocations should be made. If set to 0, then no check is made on
the number of allocations, it just grows as much as needed
The architecture-dependent code can also provide an arch_decomp_wdog()
function call. This function will be called several times during the
decompression process, and allow to notify the watchdog that the system is
still running. If an architecture provides such a call, then it must
define ARCH_HAS_DECOMP_WDOG so that the generic inflate code calls
arch_decomp_wdog().
Work initially done by Matt Mackall, updated to a recent version of the
kernel and improved by me.

This patch fixes cache memory parameter setting for the M32104 target. So
far, its performance seemed to have been degraded due to incorrect cache
parameter setting.
* arch/m32r/boot/setup.S: Set SFR(Special Fuction Registers) region
to be non-cachable explicitly.
* arch/m32r/mm/cache.c: Fix cache flushing routines not to switch off
the M32104 cache.

This patch is for supporting a new target platform, Renesas M32104UT
evaluation board.
The M32104UT is an eval board based on an uT-Engine specification. This board
has an MMU-less M32R family processor, M32104.
http://www-wa0.personal-media.co.jp/pmc/archive/te/te_m32104_e.pdf
This board is one of the most popular M32R platform, so we have ported
Linux/M32R to it.

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!
