This patch fixes a bug of ioremap_nocache. ioremap_nocache() will call __ioremap() with flags != 0 to do the real work, which will call change_page_attr_addr() if phys_addr + size - 1 < (end_pfn_map << PAGE_SHIFT). But some pages between 0 ~ end_pfn_map << PAGE_SHIFT are not mapped by identity map, this will make change_page_attr_addr failed. This patch is based on latest x86 git and has been tested on x86_64 platform.
