* mode - either "none" (LED is off) or a space separated list of one or more of:

MIPS: allow disabling the kernel FPU emulator

commit c8942f1f0a7e2160ebf2e51ba89e50ee5895a1e7
Author: Patrick McHardy <kaber@trash.net>
Date: Wed May 21 14:08:38 2008 -0700
netfilter: Move linux/types.h inclusions outside of #ifdef __KERNEL__
Greg Steuck <greg@nest.cx> points out that some of the netfilter
headers can't be used in userspace without including linux/types.h
first. The headers include their own linux/types.h include statements,
these are stripped by make headers-install because they are inside
#ifdef __KERNEL__ however. Move them out to fix this.
Reported and Tested by Greg Steuck.

+ * The first version was written by Martin Devera, <devik@cdi.cz>
+ *
+ * Credits: Jan Rafaj <imq2t@cedric.vabo.cz>
+ * - Update patch to 2.4.21
+ * Sebastian Strollo <sstrollo@nortelnetworks.com>
+ * - Fix "Dead-loop on netdevice imq"-issue
+ * Marcel Sebek <sebek64@post.cz>
+ * - Update to 2.6.2-rc1
+ *
+ * After some time of inactivity there is a group taking care
+ * of IMQ again: http://www.linuximq.net
+ *
+ *
+ * 2004/06/30 - New version of IMQ patch to kernels <=2.6.7
+ * including the following changes:
+ *
+ * - Correction of ipv6 support "+"s issue (Hasso Tepper)
+ * - Correction of imq_init_devs() issue that resulted in
+ * kernel OOPS unloading IMQ as module (Norbert Buchmuller)
+ * - Addition of functionality to choose number of IMQ devices
+ * during kernel config (Andre Correa)
+ * - Addition of functionality to choose how IMQ hooks on
+ * PRE and POSTROUTING (after or before NAT) (Andre Correa)
+ * - Cosmetic corrections (Norbert Buchmuller) (Andre Correa)
+ *
+ *
+ * 2005/12/16 - IMQ versions between 2.6.7 and 2.6.13 were
+ * released with almost no problems. 2.6.14-x was released
+ * with some important changes: nfcache was removed; After
+ * some weeks of trouble we figured out that some IMQ fields
+ * in skb were missing in skbuff.c - skb_clone and copy_skb_header.
+ * These functions are correctly patched by this new patch version.
+ *
+ * Thanks for all who helped to figure out all the problems with
+ * 2.6.14.x: Patrick McHardy, Rune Kock, VeNoMouS, Max CtRiX,
+ * Kevin Shanahan, Richard Lucassen, Valery Dachev (hopefully
+ * I didn't forget anybody). I apologize again for my lack of time.
+ *
+ *
+ * 2008/06/17 - 2.6.25 - Changed imq.c to use qdisc_run() instead
+ * of qdisc_restart() and moved qdisc_run() to tasklet to avoid
+ * recursive locking. New initialization routines to fix 'rmmod' not
+ * working anymore. Used code from ifb.c. (Jussi Kivilinna)
+ *
+ * Also, many thanks to pablo Sebastian Greco for making the initial
+ * patch and to those who helped the testing.
+ *
+ * More info at: http://www.linuximq.net/ (Andre Correa)

+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.

Paulus,
A similar patch for ppc64 made it upstream with your big ppc64 merge.
This one is still sitting in http://patchwork.ozlabs.org/linuxppc/
and didn't make it with the ppc32 equivalent. Thanks.

Subject: gpiolib: better rmmod infrastructure

gpiolib: better rmmod infrastructure
As long as one or more GPIOs on a gpio chip are used its driver should not be
unloaded. The existing mechanism (gpiochip_remove failure) doesn't address
that, since rmmod can no longer be made to fail by having the cleanup code
report errors. Module usecounts are the solution.
Assuming standard "initialize struct to zero" policies, this change won't
affect SOC platform drivers. However, drivers for external chips (on I2C and
SPI busses) should be updated if they can be built as modules.

gpiolib: dynamic gpio number allocation
If gpio_chip->base is negative during registration, gpiolib performs dynamic
base allocation. This is useful for devices that aren't always present, such
as GPIOs on hotplugged devices rather than mainboards. (This behavior was
previously specified but not implemented.)
To avoid using any numbers that may have been explicitly assigned but not yet
registered, this dynamic allocation assigns GPIO numbers from the biggest
number on down, instead of from the smallest on up.

gpiochip_reserve()
Add a new function gpiochip_reserve() to reserve ranges of gpios that platform
code has pre-allocated. That is, this marks gpio numbers which will be
claimed by drivers that haven't yet been loaded, and thus are not available
for dynamic gpio number allocation.
