MIPS has separate definitions of activate_mm() & switch_mm() which are identical apart from switch_mm() checking that the ASID is valid before acquiring a new one. We know that when activate_mm() is called cpu_context(X, mm) will be zero, and this will never be considered a valid ASID because we never allow the ASID version number to be zero, instead beginning with version 1 using asid_first_version(). Therefore switch_mm() will always allocate a new ASID when called for a new task, meaning that it will behave identically to activate_mm(). Take advantage of this to remove the duplication & define activate_mm() using switch_mm() just like many other architectures do.

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.
