Mike Kravetz c5094ec79c hugetlb: initialize variable to avoid compiler warning
With the gcc 'maybe-uninitialized' warning enabled, gcc will produce:

  mm/hugetlb.c:6896:20: warning: `chg' may be used uninitialized

This is a false positive, but may be difficult for the compiler to
determine.  maybe-uninitialized is disabled by default, but this gets
flagged as a 0-DAY build regression.

Initialize the variable to silence the warning.

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.
