From 3603ab2b62ad8372fc93816b080b370dd55d7cec Mon Sep 17 00:00:00 2001 From: Russell King Date: Sat, 5 May 2007 20:59:27 +0100 Subject: [ARM] mm 10: allow memory type to be specified with ioremap __ioremap() took a set of page table flags (specifically the cacheable and bufferable bits) to control the mapping type. However, with the advent of ARMv6, this is far too limited. Replace the page table flags with a memory type index, so that the desired attributes can be selected from the mem_type table. Finally, to prevent silent miscompilation due to the differing arguments, rename the __ioremap() and __ioremap_pfn() functions.
