Today there are two variants of set_mtrr(): one calling stop_machine() and one calling stop_machine_cpuslocked(). The first one (set_mtrr()) has only one caller, and this caller is running only when resuming from suspend when the interrupts are still off and only one CPU is active. Additionally this code is used only on rather old 32-bit CPUs not supporting SMP. For these reasons the first variant can be replaced by a simple call of mtrr_if->set(). Rename the second variant set_mtrr_cpuslocked() to set_mtrr() now that there is only one variant left, in order to have a shorter function name.

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.
