Not yet, and I didn't feel comfortable pushing it just before the 3.0.2
release, but I think _now_ would be a good time to finally merge it.
Having physical addresses in paddr seems to be common practice, and IMO
xen should follow that as it makes life easier for everybody.
It's not a big problem that xen guests boot with paging enabled, and as
Zachary already pointed out it's trivial to use virt_base from the
xen_guest elf section to create correct initial page tables.
Even maintaining backward compatibility with some guesswork is possible
as it is _very_ unlikely that the paddr field holds physical addresses
larger than virt_base ;)
cheers,
Gerd
