The /proc/iomem represents the kernel's memory map. Regions marked with "Reserved" tells the user that the range should not be tampered with. Kexec-tools, when using the older kexec_load syscall relies on the "Reserved" regions to build the memory segments, that will be the target of the new kexec'd kernel. The RISC-V port tries to expose all reserved regions to userland, but some regions were not properly exposed: Regions that resided in both the "regular" and reserved memory block, e.g. the EFI Memory Map. A missing entry could result in reserved memory being overwritten. It turns out, that arm64, and loongarch had a similar issue a while back: commit |

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 reStructuredText 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.
