Linux kernel source tree
0d3ff06733
While setting up the FDT for kexec, CPU nodes that are added after the system boots and reserved memory ranges are incorporated into the initial_boot_params (base FDT). However, they are not taken into account when determining the additional size needed for the kexec FDT. As a result, kexec fails to load, generating the following error: [1116.774451] Error updating memory reserve map: FDT_ERR_NOSPACE kexec_file_load failed: No such process Therefore, consider the extra size for CPU nodes added post-system boot and reserved memory ranges while preparing the kexec FDT. While adding a new parameter to the setup_new_fdt_ppc64 function, it was noticed that there were a couple of unused parameters, so they were removed.

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.
