To use the PC parallel port driver on Q40, we need non-standard versions of the insl/outsl accessors.

When compiling a MMU kernel with CPU_HAS_ADDRESS_SPACES=n (e.g. "MMU=y allnoconfig": "echo CONFIG_MMU=y > allno.config && make KCONFIG_ALLCONFIG=1 allnoconfig"), we use plain "move" instead of "moves", and I got: CC arch/m68k/lib/uaccess.o {standard input}: Assembler messages: {standard input}:47: Error: operands mismatch -- statement `move.b %a0,(%a1)' ignored This happens because plain "move" doesn't support byte transfers between memory and address registers, while "moves" does. Fix the asm constraints for __generic_copy_from_user(), __generic_copy_to_user(), and __clear_user() to only use data registers when accessing userspace. Also, relax the asm constraints for 16-bit userspace accesses in __put_user() and __get_user(), as both "move" and "moves" do support such transfers between memory and address registers.

'oldmant.m32[1]' is 'unsigned long' which can never be '< 0', and the original author wanted to check whether the highest bit is set. So make the bit test explicit (which is better than casting from 'unsigned long' to 'long').

Gcc may replace calls to standard string functions by open code and/or calls to other standard string functions. If the replacement function is not available out-of-line, link errors will happen. To avoid this, the out-of-line versions were provided by arch/m68k/lib/string.c, but they were usually not linked in anymore as typically none of its symbols are referenced by built-in code. However, if any module would need them, they would not be available. Hence remove the inline strcpy() and strcat() implementations, remove arch/m68k/lib/string.c, and let the generic string library code handle it. Impact on a typical kernel build seems minimal or nonexistent: - .text : 0x00001000 - 0x002aac74 (2728 KiB) - .data : 0x002ada48 - 0x00392148 ( 914 KiB) + .text : 0x00001000 - 0x002aacf4 (2728 KiB) + .data : 0x002adac8 - 0x00392148 ( 914 KiB) See also commit e00c73ee ("m68k: Remove inline strlen() implementation").
