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..
Added basic EPDC driver, including support for PXP conversions (rotation,
auto-waveform selection, CSC). Self-clock gating also supported.

commit 541cd3ee00a4fe975b22fac6a3bc846bacef37f7 ("phylib: Fix deadlock
on resume") caused TI DaVinci EMAC ethernet driver to oops upon resume:
PM: resume of devices complete after 237.098 msecs
Restarting tasks ... done.
kernel BUG at kernel/workqueue.c:354!
Unable to handle kernel NULL pointer dereference at virtual address 00000000
[...]
Backtrace:
[<c002c598>] (__bug+0x0/0x2c) from [<c0052a54>] (queue_delayed_work_on+0x74/0xf8)
[<c00529e0>] (queue_delayed_work_on+0x0/0xf8) from [<c0052b30>] (queue_delayed_work+0x2c/0x30)
The oops pops up because TI DaVinci EMAC driver detaches PHY on
suspend and attaches it back on resume. Attaching makes phylib call
phy_start_machine() that initializes a workqueue. On the other hand,
PHY's resume routine will call phy_start_machine() again, and that
will cause the oops since we just destroyed the already scheduled
workqueue.
This patch fixes the issue by moving workqueue initialization to
phy_device_create().
p.s. We don't see this oops with ucc_geth and gianfar drivers because
they perform a fine-grained suspend, i.e. they just stop the PHYs
without detaching.

Fixed bad block problems in the boot area for the i.MX23.
At this writing, UBI can't handle MTDs larger than 2GiB. If the
general use partition is larger than 2GiB, the driver will create
sub-partitions, none of which are larger than 2GiB.

Follow the approach suggested by Russell King and implemented by him in
the clkdev API and allow consumer device supply mapings to be set up
using the dev_name() for the consumer instead of the struct device.
In order to avoid making existing machines instabuggy and creating merge
issues the use of struct device is still supported for the time being.
This resolves problems working with buses such as I2C which make the
struct device available late providing that the final device name is
known, which is the case for most embedded systems with fixed setups.
Consumers must still use the struct device when calling regulator_get().

commit 221af7f87b97431e3ee21ce4b0e77d5411cf1549 upstream.
'flush_old_exec()' is the point of no return when doing an execve(), and
it is pretty badly misnamed. It doesn't just flush the old executable
environment, it also starts up the new one.
Which is very inconvenient for things like setting up the new
personality, because we want the new personality to affect the starting
of the new environment, but at the same time we do _not_ want the new
personality to take effect if flushing the old one fails.
As a result, the x86-64 '32-bit' personality is actually done using this
insane "I'm going to change the ABI, but I haven't done it yet" bit
(TIF_ABI_PENDING), with SET_PERSONALITY() not actually setting the
personality, but just the "pending" bit, so that "flush_thread()" can do
the actual personality magic.
This patch in no way changes any of that insanity, but it does split the
'flush_old_exec()' function up into a preparatory part that can fail
(still called flush_old_exec()), and a new part that will actually set
up the new exec environment (setup_new_exec()). All callers are changed
to trivially comply with the new world order.

Sizing of memory allocations shouldn't depend on the number of physical
pages found in a system, as that generally includes (perhaps a huge amount
of) non-RAM pages. The amount of what actually is usable as storage
should instead be used as a basis here.
Some of the calculations (i.e. those not intending to use high memory)
should likely even use (totalram_pages - totalhigh_pages).

Getting it is not used, let's drop support for notifications about
(un)registered events from connector.
Another option was to check credentials on receiving, but we can always
restore it without bugs if needed, but genetlink has a wider code base
and none complained, that userspace can not get notification when some
other clients were (un)registered.
