[Xen-devel] question about page_to_phys

[Xiaofeng Ling <xiaofeng.ling@xxxxxxxxx>]

The page_to_phys is defined as
#define page_to_phys(page)   (phys_to_machine(page_to_pseudophys(page)))
so it return machine addresss
while virt_to_phys return psedophys. include/asm-xen/asm-i386/io.h
this is really confusing.
why not define page_to_machine?
