[Xen-devel] about map_pages_to_xen call during boot memory allocator initialization

["余上" <yusunn@xxxxxxxxx>]

Hi All,
I know that during the initialization of boot memory allocator ,
memory is mapped into Xen's pagetable and I know this is a 1:1 mapping
under x86_32 which means the physical address equals the linear
address . So what purpose is this mapping? After all , boot allocator
just return page frame number , not the physical address the caller
must do another mapping , for example , in init_frametable .

Thank you very much
yushang
