Since the pivot being set is now reliable, the optimized loop no longer needs to find the node end. The redundant check for a dead node can also be avoided as there is no danger of using the wrong pivot since the results will be thrown out in the case of a dead node by the later check. This patch also adds a benchmark test for the function to the maple tree test framework. The benchmark shows an average increase performance of 5.98% over 3 runs with this commit.

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.
