Add struct virtqueue_ops back into the virtio core code to facilitate
the use of virtqueue implementations other than vrings. This allows
virtqueue implementations that use SMD drivers, USB drivers, or other
mechanisms for transport.
Add a new virtqueue operation, virtqueue_get_impl_size, to provide the
functionality of virtqueue_get_vring_size from the previous collapsed
implementation.
This commit partially reverts commit
7c5e9ed0c8.

When the fault injection framework introduces an error to the data
block, the current code queries the SD card to find the number of
blocks actually programmed. This value would be as requested by the
generic block layer. So the entire request would be completed.
Say, request 0 is pulled from queue and submitted. When this is being
processed, request 1 is pulled from queue and prepared. Request 0
though is successful, fault-injection framework injects an error
and modifies the bytes_xferred variable to a random value less than
requested transfer. Request 1 is not processed and during the handling
of error, the SD card is queried for the actual bytes programmed. This
would be the correct value. Thus blk_end_request would complete
this request and the control would return to fetch request 2. In this
process, request 1 is not processed at all and the application waits
indefinitely for request 1 to be processed. No further requests are
issued to the queue.
This patch identifies, if the fault injection-framework has inserted an
error to this request and doesn't query the card and uses
bytes_xferred to complete the request.

The QPNP VADC driver supports the User Bank Peripheral of
the voltage ADC(VADC).
VADC is a 15 bit ADC that measures signals through the
Main analog multiplexer (AMUX) and PREMUX. The driver
arbitrates the request to issue ADC read requests.
VADC driver includes support for the conversion sequencer.
The conversion sequencer is a HW triggered signal to start
ADC measurement on trigger events for PA ON,
camera flash and TX threshold.
The AMUX supports external pull-ups simultaneously. Clients
can select the appropriate AMUX input channel to measure the
ADC for the intended pull up configuration.

Currently when VFE requests for a free buffer, we search based
on the image mode sent from VFE. In some cases, there can be
multiple instances with the same image mode. This means the
buffer lookup logic has to take into consideration other
parameters like current usecase, vfe operation mode etc.
To ease this, add support for buffer lookup based on
the instance handle. The instance handle contains information
about where to get the buffer from. So the buffer lookup
logic does not have to know about other details. The instance
handle is decided when the user sets the format for a particular
instance. It is passed on to the VFE during AXI configuration.
VFE stores this and sends it whenever it requests for a free
buffer for a particular output.
Keep the current image_mode based buffer lookup logic for
legacy targets.

This change fixes a crash when running VCAP in de-interlace mode.
The problem was noticed in the introduction of kernel 3.4. VCAP
was improperly using the videobuf2 framework APIs. Since VCAP is
already reliant on queue structure provided by videobuf2 framework,
we created our own basic version of the qbuf and dqbuf calls that
have some similarities to the videobuf2 framework. This addition
was necessary since we are calling qbuf from a kernel work thread.
Since moving to kernel 3.4 there has been a change in videobuf2
qbuf that dereferences the current process.s mm_struct, from a
kernel work thread this struct is NULL, which was causing a crash.
When we are de-interlacing a captured video we are cycling the
buffers internally in the driver, which is why we needed to create
our own q/dq buffer functionality.
