Currently in ath9k code there is an attempt which is meant to
disable ANI for ar9100 and ar9340. But it doesn't really achieve
this. All it does is disable ANI init and setup (i.e. calls to
ath9k_hw_ani_setup and ath9k_hw_ani_init). Since ath9k_hw_ani_setup is
not called ah->config.ani_poll_interval is never initialized (i.e. it
is always zero) and ath_ani_calibrate always executes ANI procedures
(over uninitialized ANI parameters).
Moreover, ath_ani_calibrate is being called each 1ms because
common->ani.timer is set to zero interval because
ah->config.ani_poll_interval==0 (and thus smallest value of all
intervals). Normally it should not be called this often.
This patch changes the code so config.enable_ani is used to check if
ANI should be performed.
config.enable_ani is initialized to true by default. This patch sets
it to false for ar9100 and ar9340.

Turning off the radio when mac80211 tells the driver that it's idle is not
a good idea, as idle interfaces might still occasionally scan or send packets.
The only time the radio can be safely turned off is when drv_stop has been
called. In the mean time, use sc->ps_idle only to indicate network sleep vs
full sleep.
Move the LED GPIO changes out of the PCI suspend/resume path, the start/stop

After waking up from full sleep, registers are accessible, but rx/tx

ensure that a full-sleep -> wake transition is always followed by a full

The reason why this hasn't created any serious problems yet is that it's

Emmanuel noticed that when mac80211 stops the queues
for aggregation that can leave a packet pending. This
packet will be given to the driver after the AMPDU
callback, but as a non-aggregated packet which messes
up the sequence number etc.
I also noticed by looking at the code that if packets
are being processed while we clear the WANT_START bit,
they might see it cleared already and queue up on
tid_tx->pending. If the driver then rejects the new
aggregation session we leak the packet.
Fix both of these issues by changing this code to not
stop the queues at all. Instead, let packets queue up
on the tid_tx->pending queue instead of letting them
get to the driver, and add code to recover properly
in case the driver rejects the session.
(The patch looks large because it has to move two
functions to before their new use.)

We have been using i_lock to protect all kinds of data structures in the
ceph_inode_info struct, including lists of inodes that we need to iterate
over while avoiding races with inode destruction. That requires grabbing
a reference to the inode with the list lock protected, but igrab() now
takes i_lock to check the inode flags.
Changing the list lock ordering would be a painful process.
However, using a ceph-specific i_ceph_lock in the ceph inode instead of
i_lock is a simple mechanical change and avoids the ordering constraints
imposed by igrab().

ARM defines NO_IRQ to -1, but OF code relies on IRQ domains support,

When there are the same or more number of HP pins are available, HP pins
are used as the primary outputs instead of the speaker pins. But, in
some cases (especially with ALC663 & co), some DACs are available only
with a later pin and it's assigned to a speaker, and since the driver
parses the pins from the lower NID, such a DAC was skipped eventually
without assignments. This resulted in a regression, the missing speaker
volume control in the new parser.
As a workaround for this, now the driver retries the pin->DAC mapping
again after restoring the speaker-pins as primary. This is still an ad
hoc fix, but it works so far for most of Realtek codecs.

With this patch the OProfile Basic Mode Sampling support for System z
is enhanced with a counter file system. That way hardware sampling
can be configured using the user space tools with only little
modifications.
With the patch by default new cpu_types (s390/z10, s390/z196) are
returned in order to indicate that we are running a CPU which provides
the hardware sampling facility. Existing user space tools will
complain about an unknown cpu type. In order to be compatible with
existing user space tools the `cpu_type' module parameter has been
added. Setting the parameter to `timer' will force the module to
return `timer' as cpu_type. The module will still try to use hardware
sampling if available and the hwsampling virtual filesystem will be
also be available for configuration. So this has a different effect
than using the generic oprofile module parameter `timer=1'.
If the basic mode sampling is enabled on the machine and the
cpu_type=timer parameter is not used the kernel module will provide
the following virtual filesystem:
/dev/oprofile/0/enabled
/dev/oprofile/0/event
/dev/oprofile/0/count
/dev/oprofile/0/unit_mask
/dev/oprofile/0/kernel
/dev/oprofile/0/user
In the counter file system only the values of 'enabled', 'count',
'kernel', and 'user' are evaluated by the kernel module. Everything
else must contain fixed values.
The 'event' value only supports a single event - HWSAMPLING with value
0.
The 'count' value specifies the hardware sampling rate as it is passed
to the CPU measurement facility.
The 'kernel' and 'user' flags can now be used to filter for samples
when using hardware sampling.
Additionally also the following file will be created:
/dev/oprofile/timer/enabled
This will always be the inverted value of /dev/oprofile/0/enabled. 0
is not accepted without hardware sampling.

The recursion loop goes retire_requests->unbind->gpu_idle->retire_reqeusts.
Every time we go through this we need a

- and there are no other references to that object than the one from
the active list, so that it gets unbound and freed immediately.
Otherwise the recursion stops. So the recursion is only limited by the
number of objects that fit these requirements sitting in the active list
any time retire_request is called.
Issue exercised by tests/gem_unref_active_buffers from i-g-t.
There's been a decent bikeshed discussion whether it wouldn't be
