x86: construct 32-bit boot time page tables in native format.
Specifically the boot time page tables in a CONFIG_X86_PAE=y enabled kernel are in PAE format. early_ioremap is updated to use the standard page table accessors. Clear any mappings beyond max_low_pfn from the boot page tables in native_pagetable_setup_start because the initial mappings can extend beyond the range of physical memory and into the vmalloc area. Derived from patches by Eric Biederman and H. Peter Anvin. [ jeremy@goop.org: PAE swapper_pg_dir needs to be page-sized fix ] Signed-off-by: Ian Campbell <ijc@hellion.org.uk> Cc: H.
