Stafford Horne c28b27416d openrisc: Implement proper SMP tlb flushing
Up until now when flushing pages from the TLB on SMP OpenRISC was always
resorting to flush the entire TLB on all CPUs.  This patch adds the
mechanics for flushing specific ranges and pages based on the usage.

The function switch_mm is updated to account for cpu usage by updating
mm_struct's cpumask.  This is used in the SMP flush routines.

This mostly follows the riscv implementation.

README

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.
