84 * The PCI specifications (Rev 3.0, 3.2.5 "Transaction Ordering and
85 * Posting") mandate non-posted configuration transactions. This default
86 * implementation attempts to use the ioremap_np() API to provide this
87 * on arches that support it, and falls back to ioremap() on those that
88 * don't. Overriding this function is deprecated; arches that properly
89 * support non-posted accesses should implement ioremap_np() instead, which
90 * this default implementation can then use to return mappings compliant with
91 * the PCI specification.
