Hi Vivek,
This function is defined as one of arch specific fucntion set, why don't
we name it in a unified prefix as others.
And name of the default dummy function in kernel/kexec.c is not consistent
with the arch specific one, so currently
arch_image_file_post_load_cleanup of x86 arch is not called. Please
consider wihch one need be changed.
