Miaohe Lin f4bad643c1 revert "mm/z3fold.c: allow __GFP_HIGHMEM in z3fold_alloc"
Revert commit f1549cb5ab ("mm/z3fold.c: allow __GFP_HIGHMEM in
z3fold_alloc").

z3fold can't support GFP_HIGHMEM page now.  page_address is used directly
at all places.  Moreover, z3fold_header is on per cpu unbuddied list which
could be accessed anytime.  So we should remove the support of GFP_HIGHMEM
allocation for z3fold.

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.
