Accessors for the ->need_future_gp[] array are currently open-coded, which makes them difficult to change. To improve maintainability, this commit adds need_future_gp_mask() to compute the indexing mask from the array size, need_future_gp_element() to access the element corresponding to the specified grace-period number, and need_any_future_gp() to determine if any future grace period is needed. This commit also applies need_future_gp_element() to existing open-coded single-element accesses. Signed-off-by: Paul E.

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.
