PAGE_OFFSET is 0x78000000 with VMSPLIT_2G, this address is in the middle of the second pgd entry with pae enabled. This breaks assumptions (address is aligned to pgd entry's address) in a lot of places like pagetable_init. Fixing the assumptions is hard (eg, low mapping). SO I just changed the address to 0x80000000.
