To allow us to walk tables allocated into the fixmap, we need to acquire the physical address of a page, rather than the virtual address in the linear map. This patch adds new p??_page_paddr and p??_offset_phys functions to acquire the physical address of a next-level table, and changes p??_offset* into macros which simply convert this to a linear map VA. This renders p??_page_vaddr unused, and hence they are removed. At the pgd level, a new pgd_offset_raw function is added to find the relevant PGD entry given the base of a PGD and a virtual address.
