a081568d70 [ARM] Fix decompressor serial IO to give CRLF not LFCR
As per the corresponding change to the serial drivers, arrange
for ARM decompressors to give CRLF.  Move the common putstr code
into misc.c such that machines only need to supply "putc" and
"flush" functions.

4f1933620f kbuild: change kbuild to not rely on incorrect GNU make behavior
The kbuild system takes advantage of an incorrect behavior in GNU make.
Once this behavior is fixed, all files in the kernel rebuild every time,
even if nothing has changed.  This patch ensures kbuild works with both
the incorrect and correct behaviors of GNU make.

For more details on the incorrect behavior, see:

http://lists.gnu.org/archive/html/bug-make/2006-03/msg00003.html

Changes in this patch:
  - Keep all targets that are to be marked .PHONY in a variable, PHONY.
  - Add .PHONY: $(PHONY) to mark them properly.
  - Remove any $(PHONY) files from the $? list when determining whether
    targets are up-to-date or not.

f4619025a5 [ARM] Allow r2 to be passed through the decompressor to the kernel
This is part of a patch from Marc Singer to allow r2 to be
passed to the kernel.  Marc's original comments follow:

This revised R2 (atags pointer) patch incorporates comments from Nico
Pitre and Ben Dooks. It modifies the head.S files such that the R2
value set by the bootloader is conveyed to the kernel startup code.
The kernel head.S heuristically validates the pointer. It will set R2
to zero if it believes the pointer is invalid. Presently, it requires
that the ATAGS list reside in the first 16KiB of physical RAM.
Relaxing this contraint may be both desirable as well as tricky.

Patch from SAN People

Following changes were made to clock.c:

1) Replaced <asm/hardware/clock.h> with <linux/clk.h>
2) Removed old unused clk_enable & clk_disable.
3) Replaced clk_use/clk_unuse with clk_enable/clk_disable.

Otherwise it's the same as the previous patch.

0fec53a24a [ARM] Remove EPXA10DB machine support
EPXA10DB seems to be uncared for:
- the "PLD" code has never been merged
- no one has reported that this platform has been broken since
  at least 2.6.10
- interest seems to have dried up around March 2003.

Therefore, remove EPXA10DB support.

9d4f13e531 [ARM] Make kernel link address depend on PAGE_OFFSET
We are coding the kernel link address into the makefiles, which is
invisibly dependent on PAGE_OFFSET.  If PAGE_OFFSET is changed, the
makefiles also need to be changed.

Make adjustments such that the makefiles encode just the offset from
PAGE_OFFSET for the kernel link address, and use PAGE_OFFSET in the
linker scripts directly.

0f8e2d62fa [PATCH] use ${CROSS_COMPILE}installkernel in arch/*/boot/install.sh
The attached patch causes the various arch specific install.sh scripts to
look for ${CROSS_COMPILE}installkernel rather than just installkernel (in
both /sbin/ and ~/bin/ where the script already did this).  This allows you
to have e.g.  arm-linux-installkernel as a handy way to install on your
cross target.  It also prevents the script picking up on the host
/sbin/installkernel which causes the script to fall through and do the
install itself (which is what I actually use myself, with $INSTALL_PATH
set).

I don't believe it causes back-compatibility problems since calling the
host installkernel was never likely to work or be what you wanted when
cross compiling anyway.  If $CROSS_COMPILE isn't set then nothing changes.

I only use ARM and i386 myself but I figured it couldn't hurt to do the
whole lot.  I've cc'd those who I hope are the arch maintainers for files
that I've touched.

17d82fcc6a [PATCH] ARM: 2700/1: Disable IXP2000 IRQs at bootup
Patch from Deepak Saxena

The IXDP2800 bootloader does not disable IRQs before jumping into
the kernel and this is causing the Grand Unified KGDB to crash
the system when we do an early call to trap_init() and irq handlers
have not yet been registered. This patch disables IRQs before we
jump into the kernel.

1da177e4c3 Linux-2.6.12-rc2
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!
