All mapped memory is now backed by regions and we can unify and clean up io_region_validate_mmap() and io_uring_mmap(). Extract a function looking up a region, the rest of the handling should be generic and just needs the region. There is one more ring type specific code, i.e. the mmaping size truncation quirk for IORING_OFF_[S,C]Q_RING, which is left as is.

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.
