The current asm-generic/page.h only contains the get_order function, and asm-generic/uaccess.h only implements unaligned accesses. This renames the file to getorder.h and uaccess-unaligned.h to make room for new page.h and uaccess.h file that will be usable by all simple (e.g. nommu) architectures.
