Use the suspend and resume API rather than remove queue
and add queue API. The former just preempts the queue
while the latter remove it from the scheduler completely.
There is no need to do that, we only need preemption
in this case.
V2: replace queue_active with queue state
v3: set the suspend_fence_addr
v4: allocate another per queue buffer for the suspend fence, and set the sequence number.
also wait for the suspend fence. (Alex)
v5: use a wb slot (Alex)
v6: Change the timeout period. For MES, the default timeout is 2100000; /* 2100 ms */ (Alex)

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
