Lucas Stach beb311ff0f drm/etnaviv: reduce number of ktime_get calls in IRQ handler
A single IRQ might signal the completion of multiple jobs/fences
at once. There is no point in attaching a new timestamp to each
fence that only differs in when exactly the IRQ handler was able
to process this fence.

Get a single timestamp when the IRQ handler has determined that
there are completed jobs and reuse this for all fences that get
signalled by the handler.

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.
