So the entry points which are ABI and the ones I believe you're talking
about are in arch/x86/boot/compressed/head_64.S. But you have all this
stuff laid out in arch/x86/xen/ and I don't see you using the entry
points in boot/compressed/. It looks more to me that you're using the
ones in arch/x86/kernel/head_{32,64}.S after decompression.

Or am I missing something?
