Paulo Zanoni 9d9523d8c1 drm/i915: add GEN2_ prefix to the I{E, I, M, S}R registers
This discussion started because we use token pasting in the
GEN{2,3}_IRQ_INIT and GEN{2,3}_IRQ_RESET macros, so gen2-4 passes an
empty argument to those macros, making the code a little weird. The
original proposal was to just add a comment as the empty argument, but
Ville suggested we just add a prefix to the registers, and that indeed
sounds like a more elegant solution.

Now doing this is kinda against our rules for register naming since we
only add gens or platform names as register prefixes when the given
gen/platform changes a register that already existed before. On the
other hand, we have so many instances of IIR/IMR in comments that
adding a prefix would make the users of these register more easily
findable, in addition to make our token pasting macros actually
readable. So IMHO opening an exception here is worth it.

README

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.
