msm: Fix correct topology for qseecom bus scaling.

Currently, bus scaling topology for qseecom is incorrect.
 -Added the correct topology paths for accessing Crypto
  Engine which is controlled by QSEE.
 -Removed setting the clock frequency of DFAB. This is
  done by the bus driver.
 -Removed references to the dfab clock instance defined
  in clocks file.

qseecom:Fix race condition while voting for clocks

In the current functionality, if DFAB clock is already on and a
request is made to turn on SFPB clock, the DFAB clock is turned
off and SFPB clock is turned on and vice-versa.

The above situation can lead to unexpected errors. The current fix
makes sure that clocks that are on are not voted to be off without
explicit request.

msm: msm_bus: Add device tree support for bus scaling clients

This patch enables clients to specify vectors in device tree
format. Clients will no longer need to specify vectors in
the boards file. Instead, they can add the bus-scaling
related data to their own device-nodes.
The clients can then call an API exposed by the bus driver
which will build the pdata out of those strings.
The registration process using pdata remains unchanged.

    - add support for sending command to secure app loaded by

The above is needed for allowing kernel modules to communicate

qseecom: Fix failure to release qseecom handle

qseecom_release() returns a failure, if it is unable to find
app_id of zero, associated with the handle in the app list.

There exists scenarios where the handle may not have the
app_id initialized and remain to be 0.  In these scenarios,
once the uninitialized zero app_id is not found in the list,
it returns a failure.

Fix to this is look for non-zero valid app_id in the app_list when
releasing the handle.

that is already loaded will result in a failure.

Issuing a request to QSEE to check if app already exists before
issuing a request to load it, all within the same app_access_lock
mutex, fixes this issue.

sched: add PF_WAKE_UP_IDLE.

Certain workloads may benefit from the SD_SHARE_PKG_RESOURCES behavior
of waking their tasks up on idle CPUs. The feature has too much of a
negative impact on other workloads however to apply globally. The
PF_WAKE_UP_IDLE flag tells the scheduler to wake up tasks that have this
flag set, or tasks woken by tasks with this flag set, on an idle CPU
if one is available.

sched: add sysctl for controlling task migrations on wake

The PF_WAKE_UP_IDLE per-task flag made it impossible to enable
the old behavior of SD_SHARE_PKG_RESOURCES, where every task
migrates to an idle CPU on wakeup.

The sched_wake_to_idle sysctl value, when made nonzero, will cause
all tasks to migrate to an idle CPU if one is available when the
task is woken up. This is regardless of how PF_WAKE_UP_IDLE is
configured for tasks in the system. Similar to PF_WAKE_UP_IDLE,
the SD_SHARE_PKG_RESOURCES scheduler domain flag must be enabled
for the sysctl value to have an effect.

usb: gadget: u_ether: Fix memory corruption in TX path

When data aggregation is enabled, multiple skb buffers are copied
into a single USB request buffer.  When ever a USB request queue
is failed, make sure that req->length is reset to 0.  Otherwise
when the same request is used again, the stale length field is used
to access the request buffer.  This would lead to memory corruption.

The xmit function keeps the partial request at the beginning of the
queue.  Always put the idle request at the back of the queue.
