It would be helpful if we could use both `dcache_by_line_op` and `invalidate_icache_by_line` for user memory without accidentally fixing up unexpected faults when performing maintenance on kernel addresses. Let's make this possible by having both macros take an optional fixup label, and only generating an extable entry if a label is provided. At the same time, let's clean up the labels used to be globally unique using \@ as we do for other macros. There should be no functional change as a result of this patch.

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.
