Use list_for_each_entry_safe to make the code easier to follow, re-order the
checks for removal, and break once the remove flag is set in the list traversal.
SII9022 requires some platform specific data that was previously hardcoded into
the driver. Create a new siihdmi_platform_data struct to actually get this
information. This allows a particular vendor to supply the IRQ vector, the
reset method, the framebuffer id, as well as the vendor/description for the SPD
block currently.
Some usbnet drivers update link state while others do not due to
hardware limitations. Add a flag to distinguish those that do, and
set the link down initially for their devices.

* Will now parse the mode list to:
- Remove pixel clocks above 133MHz which the MX51 IPU DI cannot display (PLL limitation)
- Remove modes from mode list that are interlaced (cannot display)
- Find and save the best (native) panel mode and try and match a mode as close as possible instead of
arbitrarily trying 1280x720 (unless EDID failed for some reason)
* Reduce bus timeout default to 10ms as it always takes less (<4ms or so, but we want to handle slow monitors)
* Comment out instrumentation until it returns reasonable values (jiffies aren't accurate enough)
* Some variable renames for clearer code
Cleanup the siihdmi header (which really is pointless to split out...), redefine
the fields for the sii info frame packets, and restructure sizes to be in terms
of registers.
Use a proper edid structure definition rather than indexing into a data blob.
This also adds additional helper functions to work with the returned edid data.
There is much room for further improvements still. We should simply read the
first block, then use that to actually determine the number of blocks we need to
read from the device. We cant simply read all the potential blocks as that can
be up to 32K of data.
Once we are reading all the EDID extensions, we should iterate over the blocks
to find the CEA block rather than assuming that the device is sending the CEA
block as the first block (especially given that the VESA spec calls for block 1
to be an extension map if there are more than 1 block present).
info frame checksumming is defined by the CEA861-E standard, and is not specific
to SII9xxx, so move that into the CEA861 header.
Don't bother allocating the info frame structures off the heap. That causes
unnecessary fragmentation and complexity. Allocate them off the stack as they
are small enough. This also helps keep everything simple.
As a bonus, fixed up the SII HDMI structures and the CEA861 InfoFrame structures
in the process as well. Also clean up the magic number in the AVI InfoFrame
assertion.
drag mxc_ipuv3_fb with it (remove final efikamx specific stuff)
update some IPU stuff and ioctls for it all to interoperate
notes:
that line_length bug is still there, I really can't find why it's 0...
doesn't register because the platform_device isn't in a/a/p-mxc/devices.?
ENGR00133954 ipuv3: remove FB_SYNC_EXT flag

This actually fixes the clock sync problem with the AOC HDMI monitor we have (perfectly
working display but "input not support" floating around). Happily, the boot splash
actually works, too (previously it would not work until the second set of the display
when GDM booted). Hopefully IPU support is nice and stable now.
Support two new half-duplex SPI implementation restrictions, for links
that talk to TX-only or RX-only devices. (Existing half-duplex flavors
support both transfer directions, just not at the same time.)
Move spi_async() into the spi.c core, and stop inlining it. Then make
that function perform error checks and reject messages that demand more
than the underlying controller can support.
Based on a patch from Marek Szyprowski which did this only for the
bitbanged GPIO driver.

Currently spi_register_board_info() has to be called before its related
spi_master be registered, otherwise these board info will be just ignored.
This patch will remove this order limit, it adds a global spi master list
like the existing global board info listr. Whenever a board info or a
spi_master is registered, the spi master list or board info list
will be scanned, and a new spi device will be created if there is a
master-board info match.

With this patch spi drivers can use standard spi_driver.id_table and
MODULE_DEVICE_TABLE() mechanisms to bind against the devices. Just like
we do with I2C drivers.
This is useful when a single driver supports several variants of devices
but it is not possible to detect them in run-time (like non-JEDEC chips
probing in drivers/mtd/devices/m25p80.c), and when platform_data usage is
overkill.
This patch also makes life a lot easier on OpenFirmware platforms, since
with OF we extensively use proper device IDs in modaliases.

A number of files in drivers/spi fail checkincludes.pl due to the double
include of <linux/spi/spi_bitbang.h>.
The first include is needed to get the struct spi_bitbang definition and
the spi_bitbang_* function prototypes.
The second include happens after defining EXPAND_BITBANG_TXRX to get the
inlined bitbang_txrx_* utility functions.
The <linux/spi/spi_bitbang.h> header is also included by a number of other
spi drivers, as well as some arch/ code, in order to use struct spi_bitbang
and the associated functions.
To fix the double include, and remove any potential confusion about it, move
the inlined bitbang_txrx_* functions to a new private header in drivers/spi
and also remove the need to define EXPAND_BITBANG_TXRX.

* usb abi changes broke it
* FSL never added use_iram to urb struct ever so it never compiled in the first place
* cleanup memcpy usage so it's more readable (breaks 80 column limit but..)
Not enabled in any config. PROBABLY DOESN'T WORK. But at least it can be built and tested now.
This allows the LSM to distinguish between syslog functions originating
from /proc/kmsg access and direct syscalls. By default, the commoncaps
will now no longer require CAP_SYS_ADMIN to read an opened /proc/kmsg
file descriptor. For example the kernel syslog reader can now drop
privileges after opening /proc/kmsg, instead of staying privileged with
CAP_SYS_ADMIN. MAC systems that implement security_syslog have unchanged
behavior.

Added SWP_BLKDEV flag to distinguish block and regular file backed
swap devices. We could also check if a swap is entire block device,
rather than a file, by:
S_ISBLK(swap_info_struct->swap_file->f_mapping->host->i_mode)
but, I think, simply checking this flag is more convenient.

Devtmpfs lets the kernel create a tmpfs instance called devtmpfs
very early at kernel initialization, before any driver-core device
is registered. Every device with a major/minor will provide a
device node in devtmpfs.
Devtmpfs can be changed and altered by userspace at any time,
and in any way needed - just like today's udev-mounted tmpfs.
Unmodified udev versions will run just fine on top of it, and will
recognize an already existing kernel-created device node and use it.
The default node permissions are root:root 0600. Proper permissions
and user/group ownership, meaningful symlinks, all other policy still
needs to be applied by userspace.
If a node is created by devtmps, devtmpfs will remove the device node
when the device goes away. If the device node was created by
userspace, or the devtmpfs created node was replaced by userspace, it
will no longer be removed by devtmpfs.
If it is requested to auto-mount it, it makes init=/bin/sh work
without any further userspace support. /dev will be fully populated
and dynamic, and always reflect the current device state of the kernel.
With the commonly used dynamic device numbers, it solves the problem
where static devices nodes may point to the wrong devices.
It is intended to make the initial bootup logic simpler and more robust,
by de-coupling the creation of the inital environment, to reliably run
userspace processes, from a complex userspace bootstrap logic to provide
a working /dev.

1) remove mainline (net/wireless/usb versions) from config since they don't do anything but associate
2) port drivers/staging/ ralink drivers from Linus' tree to here
includes update to hexdump.c and kernel.h for hex_to_bin (replaces nibble, ABI change)
includes update to ralink driver source to modify usb_alloc/free_coherent to old usb_buffer_alloc/free
add it to the defconfig
You will need to grab the "Firmware RT28XX/RT30XX USB series" firmware (v 22 or above) from
http://www.ralink.com.tw/support.php?s=2
Unzip the zip file, inside is a license and rt2870.bin (an 8192 byte file). Copy this to
/lib/firmware/rt3070.bin (note the name change!) and the driver should load and work. Tested
with multiple pings, traceroutes, file copies (SCP and CIFS), YouTube..
