This reverts commit cd34db4a52 (drm/etnaviv: Remove manual call to
reservation_object_test_signaled_rcu before wait), as the patch to turn
reservation_object_wait_timeout_rcu() into
reservation_object_test_signaled_rcu() with a 0 timeout has been reverted.
This causes the driver to call into the fence wait, even with a timeout of 0
The etnaviv BO cache depends on ETNA_PREP_NOSYNC to be wait-free, even if
the BO has attached fences, so restore the behaviour for this flag.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
