Hi Benjamin,
[auto build test ERROR on linus/master]

[if your patch is applied to the wrong git tree, please drop us a note to help improve the system]

Even if CONFIG_FB_PROVIDE_GET_FB_UNMAPPED_AREA flag is selected do not compile and use get_fb_unmapped_area() if CONFIG_MMU is also set. This will avoid mmap errors when compiling multi architectures at same time.
