mainlining shenanigans

For memblock_cap_memory_range() to work properly, it should be called after memory is detected and added to memblock with memblock_add() or memblock_add_node(). If memblock_cap_memory_range() would be called before memory is registered, we may silently corrupt memory later because the crash kernel will see all memory as available. Print a warning and bail out if ordering is not satisfied.

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.
