[ Upstream commit b8e3130dd96b7b2d6d92e62dcd1515af30212fe2 ] Since a while now the uverbs layer checks if the driver implements a function before allowing the ucmd to proceed. This largely obsoletes the cmd_mask stuff, but there is some tricky bits in drivers preventing it from being removed. Remove the easy elements of uverbs_ex_cmd_mask by pre-setting them in the core code. These are triggered soley based on the related ops function pointer. query_device_ex is not triggered based on an op, but all drivers already implement something compatible with the extension, so enable it globally too.

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 Restructured Text 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.
