Subject: [PATCH] Squashfs: Factor out remaining zlib dependencies into separate wrapper file
Move zlib buffer init/destroy code into separate wrapper file. Also
make zlib z_stream field a void * removing the need to include zlib.h
for most files.

Subject: [PATCH] Squashfs: add a decompressor framework
This adds a decompressor framework which allows multiple compression
algorithms to be cleanly supported.
Also update zlib wrapper and other code to use the new framework.

Subject: [PATCH] Squashfs: add decompressor entries for lzma and lzo
Add knowledge of lzma/lzo compression formats to the decompressor
framework. For now these are added as unsupported. Without
these entries lzma/lzo compressed filesystems will be flagged as
having unknown compression which is undesirable.

Subject: [PATCH] Squashfs: Make unlzma available to non initramfs/initrd code
Add a config option DECOMPRESS_LZMA_NEEDED which allows subsystems to
specify they need the unlzma code. Normally decompress_unlzma.c is
compiled with __init and unlzma is not exported to modules.

GCC 4.4.x looks to be adding support for generating out-of-line register
saves/restores based on:
http://gcc.gnu.org/ml/gcc-patches/2008-04/msg01678.html
This breaks the kernel build as we'd have to link with libgcc to get the
implementation of the register save/restores.
To workaround this issue, we just stole the save/restore code from gcc
and simplified it down for our needs (integer only). We only do this if
PPC32 as gcc makes believe the linker on ppc64 will deal with this and
only if CONFIG_CC_OPTIMIZE_FOR_SIZE is set (thus -Os).
Signed-off-by: Kumar Gala <[EMAIL PROTECTED]>
---
If someone using cutting edge toolchains for ppc64 could test and make
sure if we enable CONFIG_CC_OPTIMIZE_FOR_SIZE things work that would be
nice.

From 2fa4341074cd02fb39aa23410740764948755635 Mon Sep 17 00:00:00 2001
From: Albin Tonnerre <albin.tonnerre@free-electrons.com>
Date: Wed, 23 Sep 2009 15:57:38 -0700
Subject: [PATCH] include/linux/unaligned/{l,b}e_byteshift.h: fix usage for compressed kernels
When unaligned accesses are required for uncompressing a kernel (such as
for LZO decompression on ARM in a patch that follows), including
<linux/kernel.h> causes issues as it brings in a lot of things that are
not available in the decompression environment.
linux/kernel.h brings at least:
extern int console_printk[];
extern const char hex_asc[];
which causes errors at link-time as they are not available when
compiling the pre-boot environement. There are also a few others:
arch/arm/boot/compressed/misc.o: In function `valid_user_regs':
arch/arm/include/asm/ptrace.h:158: undefined reference to `elf_hwcap'
arch/arm/boot/compressed/misc.o: In function `console_silent':
include/linux/kernel.h:292: undefined reference to `console_printk'
arch/arm/boot/compressed/misc.o: In function `console_verbose':
include/linux/kernel.h:297: undefined reference to `console_printk'
arch/arm/boot/compressed/misc.o: In function `pack_hex_byte':
include/linux/kernel.h:360: undefined reference to `hex_asc'
arch/arm/boot/compressed/misc.o: In function `hweight_long':
include/linux/bitops.h:45: undefined reference to `hweight32'
arch/arm/boot/compressed/misc.o: In function `__cmpxchg_local_generic':
include/asm-generic/cmpxchg-local.h:21: undefined reference to `wrong_size_cmpxchg'
include/asm-generic/cmpxchg-local.h:42: undefined reference to `wrong_size_cmpxchg'
arch/arm/boot/compressed/misc.o: In function `__xchg':
arch/arm/include/asm/system.h:309: undefined reference to `__bad_xchg'
However, those files apparently use nothing from <linux/kernel.h>, all
they need is the declaration of types such as u32 or u64, so
<linux/types.h> should be enough

netfilter: IPv6: fix DSCP mangle code
The mask indicates the bits one wants to zero out, so it needs to be
inverted before applying to the original TOS field.

+GPIOMMC - Driver for an MMC/SD card on a bitbanging GPIO SPI bus
+================================================================
+
+The gpiommc module hooks up the mmc_spi and spi_gpio modules for running an
+MMC or SD card on GPIO pins.
+
+Two interfaces for registering a new MMC/SD card device are provided:
+A static platform-device based mechanism and a dynamic configfs based interface.
+
+
+Registering devices via platform-device
+=======================================
+
+The platform-device interface is used for registering MMC/SD devices that are
+part of the hardware platform. This is most useful only for embedded machines
+with MMC/SD devices statically connected to the platform GPIO bus.
+
+The data structures are declared in <linux/mmc/gpiommc.h>.
+
+To register a new device, define an instance of struct gpiommc_platform_data.
+This structure holds any information about how the device is hooked up to the
+GPIO pins and what hardware modes the device supports. See the docbook-style
+documentation in the header file for more information on the struct fields.
+
+Then allocate a new instance of a platform device by doing:
+
+ pdev = platform_device_alloc(GPIOMMC_PLATDEV_NAME, gpiommc_next_id());
+
+This will allocate the platform device data structures and hook it up to the
+gpiommc driver.
+Then add the gpiommc_platform_data to the platform device.
+
+ err = platform_device_add_data(pdev, pdata, sizeof(struct gpiommc_platform_data));
+
+You may free the local instance of struct gpiommc_platform_data now. (So the
+struct may be allocated on the stack, too).
+Now simply register the platform device.
+
+ err = platform_device_add(pdev);
+
+Done. The gpiommc probe routine will be invoked now and you should see a kernel
+log message for the added device.
+
+
+Registering devices via configfs
+================================
+
+MMC/SD cards connected via GPIO often are a pretty dynamic thing, as for example
+selfmade hacks for soldering an MMC/SD card to standard GPIO pins on embedded
+hardware are a common situation.
+So we provide a dynamic interface to conveniently handle adding and removing
+devices from userspace, without the need to recompile the kernel.
+
+The "gpiommc" subdirectory at the configfs mountpoint is used for handling
+the dynamic configuration.
+
+To create a new device, it must first be allocated with mkdir.
+The following command will allocate a device named "my_mmc":
+ mkdir /config/gpiommc/my_mmc
+
+There are several configuration files available in the new
+/config/gpiommc/my_mmc/ directory:
+
+gpio_data_in = The SPI data-IN GPIO pin number.
+gpio_data_out = The SPI data-OUT GPIO pin number.
+gpio_clock = The SPI Clock GPIO pin number.
+gpio_chipselect = The SPI Chipselect GPIO pin number.
+gpio_chipselect_activelow = Boolean. If 0, Chipselect is active-HIGH.
+ If 1, Chipselect is active-LOW.
+spi_mode = The SPI data mode. Can be 0-3.
+spi_delay = Enable all delays in the lowlevel bitbanging.
+max_bus_speed = The maximum SPI bus speed. In Hertz.
+
+register = Not a configuration parameter.
+ Used to register the configured card
+ with the kernel.
+
+The device must first get configured and then registered by writing "1" to
+the "register" file.
+The configuration parameters "gpio_data_in", "gpio_data_out", "gpio_clock"
+and "gpio_chipselect" are essential and _must_ be configured before writing
+"1" to the "register" file. The registration will fail, otherwise.
+
+The default values for the other parameters are:
+gpio_chipselect_activelow = 1 (CS active-LOW)
+spi_mode = 0 (SPI_MODE_0)
+spi_delay = 1 (enabled)
+max_bus_speed = 5000000 (5 Mhz)
+
+Configuration values can not be changed after registration. To unregister
+the device, write a "0" to the "register" file. The configuration can be
+changed again after unregistering.
+
+To completely remove the device, simply rmdir the directory
+(/config/gpiommc/my_mmc in this example).
+There's no need to first unregister the device before removing it. That will
+be done automatically.
