The changes for this release include power management improvements for
the pwm-img driver, support for the backup mode on pwm-atmel-tcb as well
as support for more hardware with the R-Car and Mediatek drivers.
To round things off there's a bit of cleanup for sunxi and stm32-lp.

When the function tipc_group_filter_msg() finds that a member event
indicates that the member is leaving the group, it first deletes the
member instance, and then purges the message queue being handled
by the call. But the message queue is an aggregated field in the
just deleted item, leading the purge call to access freed memory.
We fix this by swapping the order of the two actions.

On some systems, when we unsplit a port we need to re-create two ports
instead. On other systems, only one needs to be re-created.
Do not try to create a port if during driver initialization it was
assigned a negative module number, which is invalid.
This avoids the following error during unsplit:
[ 941.012478] mlxsw_spectrum 0000:01:00.0: Port 43: Failed to map module
The error is harmless and caused by the fact that a local port is
already mapped to module 0.

Profiles that have an undecidable overlap in their attachments are
being incorrectly handled. Instead of failing to attach the first one
encountered is being used.
eg.
profile A /** { .. }
profile B /*foo { .. }
have an unresolvable longest left attachment, they both have an exact
match on / and then have an overlapping expression that has no clear
winner.
Currently the winner will be the profile that is loaded first which
can result in non-deterministic behavior. Instead in this situation
the exec should fail.

gcc-4.4 points out suspicious code in compute_mnt_perms, where
the aa_perms structure is only partially initialized before getting
returned:
security/apparmor/mount.c: In function 'compute_mnt_perms':
security/apparmor/mount.c:227: error: 'perms.prompt' is used uninitialized in this function
security/apparmor/mount.c:227: error: 'perms.hide' is used uninitialized in this function
security/apparmor/mount.c:227: error: 'perms.cond' is used uninitialized in this function
security/apparmor/mount.c:227: error: 'perms.complain' is used uninitialized in this function
security/apparmor/mount.c:227: error: 'perms.stop' is used uninitialized in this function
security/apparmor/mount.c:227: error: 'perms.deny' is used uninitialized in this function
Returning or assigning partially initialized structures is a bit tricky,
in particular it is explicitly allowed in c99 to assign a partially
initialized structure to another, as long as only members are read that
have been initialized earlier. Looking at what various compilers do here,
the version that produced the warning copied uninitialized stack data,
while newer versions (and also clang) either set the other members to
zero or don't update the parts of the return buffer that are not modified
in the temporary structure, but they never warn about this.
In case of apparmor, it seems better to be a little safer and always
initialize the aa_perms structure. Most users already do that, this
changes the remaining ones, including the one instance that I got the
warning for.

When deleting a station or otherwise tearing down all aggregation
sessions, make sure to delete requested but not yet started ones,
to avoid the following scenario:
* session is requested, added to tid_start_tx[]
* ieee80211_ba_session_work() runs, gets past BLOCK_BA check
* ieee80211_sta_tear_down_BA_sessions() runs, locks &sta->ampdu_mlme.mtx,
e.g. while deleting the station - deleting all active sessions
* ieee80211_ba_session_work() continues since tear down flushes it, and
calls ieee80211_tx_ba_session_handle_start() for the new session, arms
the timer for it
* station deletion continues to __cleanup_single_sta() and frees the
session struct, while the timer is armed

When cfg80211 is built as a module, everything is fine, and we
can keep the code as is; in fact, we have to, because there can
only be a single module_init().
When cfg80211 is built-in, however, it needs to initialize
before drivers (device_initcall/module_init), and thus used to
be at subsys_initcall(). I'd moved it to fs_initcall() earlier,
where it can remain. However, this is still too early because at
that point the key infrastructure hasn't been initialized yet,
so X.509 certificates can't be parsed yet.
To work around this problem, load the regdb keys only later in
a late_initcall(), at which point the necessary infrastructure
has been initialized.

In rare cases, ena driver would reset and re-start the device,
for example, in case of misbehaving application that causes
transmit timeout
The first step in the reset procedure is to stop the Tx traffic by
calling ena_carrier_off().
After the driver have just started the device reset procedure, device
happens to send an asynchronous notification (via AENQ) to the driver
than there was a link change (to link-up state).
This link change is mapped to a call to netif_carrier_on() which
re-activates the Tx queues, violating the assumption of no tx traffic
until device reset is completed, as the reset task might still be in
the process of queues initialization, leading to an access to
uninitialized memory.

Commit b65a9cfc2c ("Untangling ima mess, part 2: deal with counters")
moved the call of ima_file_check() from may_open() to do_filp_open() at a
point where the file descriptor is already opened.
This breaks the assumption made by IMA that file descriptors being closed
belong to files whose access was granted by ima_file_check(). The
consequence is that security.ima and security.evm are updated with good
values, regardless of the current appraisal status.
For example, if a file does not have security.ima, IMA will create it after
opening the file for writing, even if access is denied. Access to the file
will be allowed afterwards.
Avoid this issue by checking the appraisal status before updating
security.ima.

Name of functions rtl_w0w1_eri and rtl_w0w1_phy is somewhat misleading
regarding order of arguments. One could assume that w0w1 means
argument with bits to be reset comes before argument with bits to set.
However this is not the case.
So fix the order of arguments in several statements.
In addition fix EEE advertisement. The current code resets the bits
for 100BaseT and 1000BaseT EEE advertisement what is not what we want.
I have a little of a hard time to find a proper "Fixes" line as the
issue seems to have been there forever (at least it existed already
when the driver was moved to the current place in 2011).
