When set_pmd_at is called in function do_huge_pmd_anonymous_page, new tlb
entry can be added by software on MIPS platform.

Here add update_mmu_cache_pmd when pmd entry is set, and
update_mmu_cache_pmd is defined as empty excepts arc/mips platform.  This
patch has no negative effect on other platforms except arc/mips system.

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.
