 * writew/writel functions and the other mmio helpers. The returned
 * address is not guaranteed to be usable directly as a virtual
 * address.
 *

 *
 * * ioremap is the standard one and provides non-cacheable guarded mappings
 *   and can be hooked by the platform via ppc_md
 *
 * * ioremap_prot allows to specify the page flags as an argument and can
 *   also be hooked by the platform via ppc_md.
 *
 * * ioremap_nocache is identical to ioremap
 *
 * * ioremap_wc enables write combining
 *
 * * iounmap undoes such a mapping and can be hooked
 *
 * * __ioremap_at (and the pending __iounmap_at) are low level functions to
 *   create hand-made mappings for use only by the PCI code and cannot
 *   currently be hooked. Must be page aligned.
 *
 * * __ioremap is the low level implementation used by ioremap and
 *   ioremap_prot and cannot be hooked (but can be used by a hook on one
 *   of the previous ones)
 *
 * * __ioremap_caller is the same as above but takes an explicit caller
 *   reference rather than using __builtin_return_address(0)
