I agree. Some of them are already identical, some are not but the QEMU
version should be okay, and for yet more it's probably better to keep
the Xen-specific parts in hvmloader.
The good thing is that it's possible to proceed incrementally once you
have the hvmloader support for merging the QEMU and hvmloader RSDT or
XSDT (whatever you are using), starting with just NVDIMM and proceeding
later with whatever you see fit.
