xenheap size is 9M on x86/32 xen, it's not enough to setup 1:1 mapping page table for dom0. It causes dom0 cannot boot successfully. Instead of xenheap, this patch setup 1:1 mapping page tabel in domheap, and use map_domain_page() to get temporary mappings when need them. Signed-off-by: Weidong Han <weidong.han@xxxxxxxxx>
