This should probably be ioremap_wc. Otherwise it will be *really* slow if used in legacy mode and it may cause conflicts with the pgprot_writecombine mode for mmap.
(Watching boot messages go by on fbcon on efifb was like using an old 2400 baud modem before I made the corresponding change to efifb.)
