When a kernel thread calls dma_buf_put() to release the last reference
to a dma-buf, fput_many() defers calling the release callback to a
workqueue. This means that if the same kernel thread later calls
dma_heap_buffer_alloc(), it has no guarantee that the memory from the
prior free is available, leading to random failures. As a short-term
workaround, call flush_delayed_fput() to ensure the free completes
synchronously.

When below sequence is run back-to-back, -ENOMEM is occasionally returned
by MEM_BUF_IOC_REMOTE_ALLOC.
ioctl(MEM_BUF_IOC_REMOTE_ALLOC, args)
fd = args.fd
close(fd)
This occurs because the message sent from TUIVM to PVM as part of the
file release callback is asynchonous. Resolve this by adding a new
message type which indicates when PVM has completed the free operation.
Additionally, define a separate obj_id instead of reusing the transaction
id for this purpose.

Reuse the same buffer for each message in mem_buf_msgq_recv_fn()
instead of allocating a new one for each message, and freeing it
in a dozen different locations depending on what type of message it
is.
If a consumer of the message needs to defer its work to a workqueue,
it must allocate a new copy of the message.

add_memory_subsection() and remove_memory_subsection() are only needed
on the TVM and OEM VMs. These are downstream functions as well. Thus,
selectively allow them to be enabled so that we only compile them on
downstream kernels.

Currently the code subtracts busy time when a task is being migrated.
IOW migrate_busy_time_subtraction is called in set_task_cpu hook.
And the code adds busy time in an after-migration enqueue IOW
enqueue_after_migration is seen set in enqueue hook.
Both the above operations happen under the prev_cpu and next cpu rq
lock respt.
Now a task could exit or enter group after the migration and before
the enqueue i.e. transfer_busy_time could be called when
enqueue_after_migration is set. This could lead to -ve load bugs as
we have only subtracted the load and not added it.
To address this, complete the addition step in
transfer_busy_time() itself, prior to moving the busy time,
if a task is found to be migrating.

This is a debug feature where a kernel panic is triggered when
pdr notification to the APPS client is taking too long. This scenario
can happen if the one of notifier gets stuck and due to which subsystem
did not get ack back from APPS in time and trigger timeout panic.
So, trigger a kernel panic in APPS if PDR notifications is taking
too long.
