Linus Torvalds 377bf660d0 Revert "mm: fix initialization of struct page for holes in memory layout"
This reverts commit d3921cb8be29ce5668c64e23ffdaeec5f8c69399.

Chris Wilson reports that it causes boot problems:

 "We have half a dozen or so different machines in CI that are silently
  failing to boot, that we believe is bisected to this patch"

and the CI team confirmed that a revert fixed the issues.

The cause is unknown for now, so let's revert it.

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.
