This patch adds the support code needed for implementing kexec_file_load() on powerpc. This consists of functions to load the ELF kernel, either big or little endian, and setup the purgatory enviroment which switches from the first kernel to the second kernel. None of this code is built yet, as it depends on CONFIG_KEXEC_FILE which we have not yet defined. Although we could define CONFIG_KEXEC_FILE in this patch, we'd then have a window in history where the kconfig symbol is present but the syscall is not, which would be awkward.
