This reverts commit 1d6cd2146c which was
mistakenly added into v6.6.y and the commit corresponding to the 'Fixes:'
tag is invalid. For more information, see link [1].
This will result in the loss of Crashkernel data in /proc/iomem, and kdump
failed:
```
Memory for crashkernel is not reserved
Please reserve memory by passing"crashkernel=Y@X" parameter to kernel
Then try to loading kdump kernel
```
After revert, kdump works fine. Tested on QEMU riscv.

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.
