Error prints for commands that are broadcasted may spam the kernel logs
if a client is misbehaving and stops reading from it's socket.
Change these prints to ratelimited in order to prevent performance
issues when a client socket is full.

Add some more information to command prints in ipc logging and rename
logs from 'ns' to 'qrtr_ns' to group all qrtr logs together.

With USB QDSS software path disable case, usb_qdss_close() API tries to
dequeue all queued USB requests which may have been already moved to
cancelled list and unlikely available as those may have been already
given back from end xfer command. There are more than 200 USB request
and quick enable/disable of USB QDSS software path results into error
message flooding serial console possibly causign watchdog timeout.
Hence rate limit error message with ep_dequeue() API.

Attempt to online memory before invoking the oom-killer
to alleviate the memory pressure in the system as quickly
as possible, without sacrificing performance/user-experience
by invoking the oom-killer.

The logic to walk through the memory blocks in the movable
zone is not correct. When memory at either extreme of the movable
zone is offlined, the start of the movable zone is adjusted such that
it no longer accounts for the block that was offlined--if the block
is at the beginning of the movable zone--or the span of the movable
zone is adjusted such that it no longer covers the block that was
offlined--if the block is at the end of the movable zone. Similarly,
when the entire zone is offlined, the zone's start pfn and span are
set to 0. So, when looking for a block to online, we end up ignoring
some of the blocks at the extremes of the movable zone, or the entire
zone.
Thus, walk through all of the present memory blocks in the system when
deciding to online a block.

There is a possible scenario where the system can deadlock
itself when it is low on memory, and attempts to online
a memory block. Consider the following scenario:
-A thread in userspace onlines a memory block through sysfs-
state_store() /* Acquires the device_hotplug_lock */
device_online()
memory_subsys_online()
memory_block_change_state()
memory_block_action()
online_pages()
memory_notify(MEM_GOING_ONLINE, ...)
online_page_ext()
alloc_page_ext()
__alloc_pages_nodemask(GFP_KERNEL, ...)
/* System enters into a critically low memory state */
out_of_memory()
try_online_one_block() /* Invokes lock_device_hotplug() and deadlocks */
Fix deadlock by introducing and using trylock_device_hotplug()
instead of lock_device_hotplug().

Headset is not detected after system goes into suspend
as sufficient delay is not given after pm_stay_awake
for system to wakeup. Implementing freezable workqeueue
after pm_stay_awake resolves the issue.
