Can't the memcpy be done in asm? We have arch/powerpc/lib/memcpy_64.S
for example, perhaps it could be linked in with the purgator
Right now purgatory implementation is only minimal. But if purgatory
code is to be enhanced to copy memory to the backup region and verify
sha256 digest, relocations may have to be applied to the purgatory.
So, add support to relocate purgatory in kexec_file_load system call
by setting up TOC point
