Looks like the only place you use the xen_phys_start and xenheap_phys_end.
Of course xenheap_phys_* no longer even exist on x86/64. The best you can do
I think is [__pa(&_start), __pa(&_end)]. If you want to do better for i386
(though frankly hardly anyone uses that build) then you can use
[xenheap_phys_start, xenheap_phys_end] and update xenheap_phys_start to
(1ul<<20) in setup.c. Please leave xen_phys_start alone and don't use it.
