[Xen-devel] Is machine_to_phys_mapping a 4MB 'superpage'?

[Jacob Gorm Hansen <jacobg@xxxxxxx>]

hi,

The machine_to_phys_mapping table is mapped permanently at 0xFC000000 
(on x86-32). I would like to experiment with letting the domU map it at 
other locations in its virtual address space, but I suppose that for 
performance it is mapped as a 4MB 'super' page, and as such needs 
special treatment, is this correct?
Thanks,
Jacob
