mdp to hang up. Add mdp underflow recovery mechanism  when mdp
underflow detected.

fat: limit the number of error prints

Use fat_fs_error_ratelimit instead of fat_fs_error so as to

sd: call blk_pm_runtime_init before add_disk

Sujit has found a race condition that would make q->nr_pending
unbalanced, it occurs as Sujit explained:

"
sd_probe_async() ->
	add_disk() ->
		disk_add_event() ->
			schedule(disk_events_workfn)
	sd_revalidate_disk()
	blk_pm_runtime_init()
return;

Let's say the disk_events_workfn() calls sd_check_events() which tries
to send test_unit_ready() and because of sd_revalidate_disk() trying to
send another commands the test_unit_ready() might be re-queued as the
tagged command queuing is disabled.

So the race condition is -

Thread 1 			  |		Thread 2
sd_revalidate_disk()		  |	sd_check_events()
...nr_pending = 0 as q->dev = NULL|	scsi_queue_insert()
blk_runtime_pm_init()		  | 	blk_pm_requeue_request() ->
				  |	nr_pending = -1 since
				  |	q->dev != NULL
"

The problem is, the test_unit_ready request doesn't get counted the
first time it is queued, so the later decrement of q->nr_pending in
blk_pm_requeue_request makes it unbalanced.

Fix this by calling blk_pm_runtime_init before add_disk so that all
requests initiated there will all be counted.

scsi: Allow auto suspend override by low-level driver

Until now the scsi mid-layer forbids runtime suspend till userspace
enables it. This is mainly to quarantine some disks with broken
runtime power management or have high latencies executing suspend
resume callbacks. If the userspace doesn't enable the runtime suspend
the underlying hardware will be always on even when it is not doing
any useful work and thus wasting power.

Some low-level drivers for the controllers can efficiently use runtime
power management to reduce power consumption and improve battery life.
Allow runtime suspend parameters override within the LLD itself
instead of waiting for userspace to control the power management.

msm: ipc: Serialize SMD XPRT CLOSE and OPEN events

When a remote subsystem resets, IPC Router's SMD XPRT Layer queues a CLOSE
event. When the concerned subsytem powers up and the channel is reopened,
SMD XPRT Layer queues a OPEN event. When the remote subsytem resets and
powers up quickly, the following race condition exists:
a) IPC Router is scheduled out while handling the CLOSE event, leaving a
   stale XPRT
b) IPC Router's SMD XPRT Layer queues a OPEN event
c) IPC Router's SMD XPRT Layer reads a HELLO message, finds a stale
   XPRT and queues a DATA event on the stale XPRT
This race condition causes a kernel panic.

Fix this race condition, by not handling any other SMD XPRT event until
the CLOSE event is complete.

msm: ipc: Send Resume_Tx from the client/server context

Resume_tx is passed by IPC Router as soon as it detects confirm_rx
field being set in received message. In a scenario where the local port
towards which the confirm_rx is directed is not in a state of accepting
messages, this behavior of IPC Router makes the remote port send more
data towards the local port. In addition, in a multi-hop scenario the
resume_tx message holds the destination node_id as the value of the
neighbouring node_id which is incorrect.

Pass Resume_Tx from the context of the thread to which the local port is
associated. Pass the right node_id as destination node_id in the
Resume_Tx message.

msm: ipc: Fix memory leak

When IPC Router detects a data packet from an unknown remote port,
the router creates a remote port. In case of failure while creating the
remote port, router doesn't free the memory allocated to the data packet.
This leads to memory leak beacuse once the above mentioned failure
occurs, the data packet never gets used.

Fix the memory leak in case of failure while creating the remote port.
