The commit (bce492c0 ARM: OMAP2+: UART: Fix incorrect population of
default uart pads) removed default uart pads that where getting populated
and which was making rx pin wakeup capable. If uart pads were used in
different mode by any other module then it would fail since the default
pads took over all the uart pins forcefully. With removal of default pads
the rx_pad wakeup for console uart while waking up from off mode is broken.
Utilise the mux api available to probe the availability of mux pins
in uart mode and probe for availability of uart pin in mux mode0
if uart is available as uart pin itself then configure rx pin
as wakeup capable.
This patch itself doesn't cater to all boards. Boards using uart rx wakeup
mechanism should ensure the usage of omap_serial_init_port by configuring
required uart ports and pass necessary mux data, till then this probing of
uart pins can cater to enabling of rx pad wakeup to most of the boards.
This patch can also throw some boot warning from _omap_mux_get_by_name
if pin is requested for availability is not present while dynamically probing
the uart pins availability such boot warnings can be addressed only when board
files are patched with omap_serial_init_port calls passing the right pads
needed for a given port.

Many TVs and A/V receivers don't work with this bit set. Problem was
confirmed using: Onkyo TX-SR605, Sony BRAVIA KDL-52X3500, Sony BRAVIA
KDL-40S40xx. In theory this bit shouldn't affect audio engine when
feeding it with data, however it seems it does. Driver fglrx doesn't set
that bit in any of the above cases.
This fixes a regression introduced by 3.5-rc1.

There is no guarantee that the last reference to the iio device has already been
dropped when iio_device_free is called. This means that we can up calling
iio_dev_release after iio_device_free which will lead to a use after free. As
the general rule the struct containing the device should always be freed in the
release callback.
This is what this patch does, it moves freeing the iio device struct as well as
releasing the idr reference to the release callback. To ensure that the device
is not freed before calling iio_device_free the device_unregister call in
iio_device_unregister is broken apart. iio_device_unregister will now only call
device_del to remove the device from the system and iio_device_free will call
put_device to drop the reference we obtained in iio_devce_alloc.
We also have to take care that calling iio_device_free without having called
iio_device_register still works (i.e. this can happen if something failed during
device initialization). For this to work properly two minor changes were
necessary: channel_attr_list needs to be initialized in iio_device_alloc and we
have to check whether the chrdev has been registered before releasing it in
iio_device_release.
This change also brings iio_device_unregister and iio_device_free more in sync
with iio_device_register and iio_device_alloc which call device_add and
device_initialize respectively.

Pull frontswap feature from Konrad Rzeszutek Wilk:
"Frontswap provides a "transcendent memory" interface for swap pages.
In some environments, dramatic performance savings may be obtained
because swapped pages are saved in RAM (or a RAM-like device) instead
of a swap disk. This tag provides the basic infrastructure along with
some changes to the existing backends."
Fix up trivial conflict in mm/Makefile due to removal of swap token code
changing a line next to the new frontswap entry.
This pull request came in before the merge window even opened, it got
delayed to after the merge window by me just wanting to make sure it had
actual users. Apparently IBM is using this on their embedded side, and
Jan Beulich says that it's already made available for SLES and OpenSUSE
users.
Also acked by Rik van Riel, and Konrad points to other people liking it
too. So in it goes.

When any interface goes down, it could be the one that we
were doing a remain-on-channel with. We therefore need to
cancel the remain-on-channel and flush the related work
structs so they don't run after the interface has been
removed or even destroyed.
It's also possible in this case that an off-channel SKB
was never transmitted, so free it if this is the case.
Note that this can also happen if the driver finishes
the off-channel period without ever starting it.

As part of hardware reconfig mac80211 tries
to restore the station state to its values
before the hardware reconfig, but it only
goes to the last-state - 1. Fix this
off-by-one error.

Since my commit
iwlwifi: use valid TX/RX antenna from hw_params
the config values are pure overrides, not the
real values for all hardware. Therefore, the
EEPROM TX power reading code checks the wrong
values, it should check the hw_params values.

Mesh station that joins an MBSS is reachable using mesh portal with 6
address frame by mesh stations from another MBSS if these two different
MBSSes are bridged. However, if the mesh station later moves into the
same MBSS of those mesh stations, it is unreachable by mesh stations
in the MBSS due to the mpp_paths table is not deleted. A quick fix
is to perform mesh_path_lookup, if it is available for the target
destination, mpp_path_lookup is not performed. When the mesh station
moves back to its original MBSS, the mesh_paths will be deleted once
expired. So, it will be reachable using mpp_path_lookup again.

CFG80211_DEV_WARN_ON() at "net/wireless/ibss.c line 63"
is unnecessarily triggered even after successful connection,
when cfg80211_ibss_joined() is called by driver inside
.join_ibss handler.
This patch fixes the problem by changing 'sme_state' in ibss path
and having WARN_ON() check for 'sme_state' similar to infra
association.
