[PATCH 6/15] ptwalk: ioremap_page_range

Convert i386 ioremap pagetable walkers to loops using p?d_addr_end. Rename internal levels ioremap_p??_range. Don't cheat, give it a real (but inlined) ioremap_pud_range; uninline lowest level to help debug. Replace "page already exists" printk and BUG by BUG_ON. Signed-off-by: Hugh Dickins
