Currently range_is_memory finds the corresponding struct memblock_region for both the lower and upper bounds of the given address range with two rounds of binary search, and then checks that the two memblocks are the same. Simplify this by only doing binary search on the lower bound and then checking that the upper bound is in the same memblock.

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.
