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

Use the gpuaddr to determine whether memstore is being mapped in
mmap or a normal memory allocation is mapped instead of physical
address. gpuaddr of the memstore will always be unique but the
physaddr may be equal to the gpuaddr of another memory allocation
and that will cause the memory allocation to be mapped as memstore
which is wrong.

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 RPM provides an interface to vote for XO buffers. These
buffers can either be in software control or in pin control
mode. Provide separate RPM clocks per buffer for each mode.
Enabling a pin-control-mode clock will set the buffer in pin
control mode. Enabling a software-mode clock will enable the
buffer. Disabling works the same for both types of clocks -
the buffer is disabled.
On the RPM, the votes for pin-control versus software-enable
are separately aggregated. Software-enable has higher priority
over pin-control, and if the software-mode aggregation results
in a disable, pin-control will still be configured if there is
a pin-control vote in place.

When the system goes to sleep, the power management code sends a sleep
set to RPM. The code executes with interrupts disabled so the power
management code polls for ack message from RPM. Since the SMD interrupt
is in a triggered state and irq handler hasn't had a chance to run, the
pending interrupt prevent the Core from entering a low power mode.
To prevent interrupt from waking the system up, disable/enable the RPM to
SMD interrupt while entering/exiting sleep mode, by calling into the SMD
API.

SMD is used for communicating power state with the RPM processor.
During a power-down sequence, sleep information is transferred to the

RPM sends the response, it triggers an interrupt which then causes the
Application processor to abort the power-down sequence.
Add a new function that allows interrupts to be masked/unmasked for an
entire subsystem which allows the power code to mask interrupts while
powering down to prevent aborting the power-down sequence.

The BT host has fixed set of buffers to send data to SoC, generic value
is 5. When a connection, like A2DP playback is ready to send data it
fills one of the buffer available and sends to SoC. Once SoC got
acknowledged from remote side that the data received it updates the host
and the buffer is freed. Till host is acknowledged the send Complete
info, the data buffer is locked for that data transfer. The below is the
example for buffers availability.
Total free Buffers count : 5
Connections : 1
Conn_1 need to send data, picks buf_1 and send to SoC
free Buffers count: 4
Buffers used by Conn_1 : 1
Still Conn_1 has more data to send ....
free Buffers count: 3
Buffers used by Conn_1 : 2
Remote device Ack for buf_1, so 1 buffer is freed, updated state is
free Buffers count : 4
Buffers used by Conn_1 : 1
When there are more ACL connections to transfer data, like one
connection for A2DP playback and one for OPP data transfer, all the data
buffers available with host can be used by any ACL which has ready data
to send. This allows maximum throughputs possibility from host. But the
existing solution has a problem. If one connection has used all the
buffers at a instanace of time, and didnt release (this happens when remote
device doesnt ACK to send) the other connections will not have buffers to
send. In current usecase A2dp data cannot be sent to headset as OPP
connection is lost. The current change is, when there are more
connections the quota for a connection that it can use maximum is
total buffers-1. This allows other connections not to get blocked,
at the same time through puts are not going to dropped.
