Miaohe Lin 55c7ac4527 mm: memory-failure: use local variable huge to check hugetlb page
Use local variable huge to check whether page is hugetlb page to avoid
calling PageHuge() multiple times to save cpu cycles.  PageHuge() will be
stable while extra page refcnt is held.

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.
