How is the relocation address decided for x86-64 Xen? Since trampoline
code still uses 0x90000 as the case before relocation change, I guess
wakeup code can still work since it's hard coded to 0x7000 by far. As
long as 0-1M is still special owned by dom_io (not participate into heap
allocation), I guess that wakeup code should still work.
Thanks,
Kevin
