John Hubbard 20622d5544 x86/boot: Fix boot regression caused by bootparam sanitizing
commit 7846f58fba upstream.

commit a90118c445 ("x86/boot: Save fields explicitly, zero out everything
else") had two errors:

    * It preserved boot_params.acpi_rsdp_addr, and
    * It failed to preserve boot_params.hdr

Therefore, zero out acpi_rsdp_addr, and preserve hdr.

Fixes: a90118c445 ("x86/boot: Save fields explicitly, zero out everything else")

============

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
