Currently the page offset is hard coded to 0xe000000000000000UL
at compile time of kexec-tools. This patch changes things around
so the page offset is handed to purgatory by the kexecing kernel.
Note that this changes the ABI between purgatory (part of kexec-tools)
and the kernel kexec code. There is an accomanying kexec-tools patch.
