Kairui Song 4c5b566c21 crash_dump: Remove no longer used saved_max_pfn
saved_max_pfn was originally introduced in commit

  92aa63a5a1 ("[PATCH] kdump: Retrieve saved max pfn")

It used to make sure that the user does not try to read the physical memory
beyond saved_max_pfn. But since commit

  921d58c0e6 ("vmcore: remove saved_max_pfn check")

it's no longer used for the check. This variable doesn't have any users
anymore so just remove it.

 [ bp: Drop the Calgary IOMMU reference from the commit message. ]

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.
