Now that RCU no longer relies on failsafe checks, cpu_needs_another_gp() can be greatly simplified. This simplification eliminates the last call to rcu_future_needs_gp() and to rcu_segcblist_future_gp_needed(), both of which which can then be eliminated. And then, because cpu_needs_another_gp() is called only from __rcu_pending(), it can be inlined and eliminated. This commit carries out the simplification, inlining, and elimination called out above.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
