The fields ima_buffer_addr and ima_buffer_size in "struct kimage_arch" for powerpc are used to carry forward the IMA measurement list across kexec system call. These fields are not architecture specific, but are currently limited to powerpc. arch_ima_add_kexec_buffer() defined in "arch/powerpc/kexec/ima.c" sets ima_buffer_addr and ima_buffer_size for the kexec system call. This function does not have architecture specific code, but is currently limited to powerpc. Move ima_buffer_addr and ima_buffer_size to "struct kimage". Set ima_buffer_addr and ima_buffer_size in ima_add_kexec_buffer() in security/integrity/ima/ima_kexec.c.

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.
