Hence move the fonts and their support logic from drivers/video/console/ to

This also allows to limit processing of drivers/video/console/Makefile to

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)

pci_scan_bus() has called pci_bus_add_devices() already, so remove the
redundant call of pci_bus_add_devices(). subsys_init() callbacks will be
invoked before device_init() callbacks, so it should be safe to remove the
redundant calls.

"A boot lock-up on Mac, also destined for stable"
* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/geert/linux-m68k:
m68k/mac: Fix unexpected interrupt with CONFIG_EARLY_PRINTK
The present code does not wait for the SCC to finish resetting itself
before trying to initialise the device. The result is that the SCC
interrupt sources become enabled (if they weren't already). This leads to
an early boot crash (unexpected interrupt) given CONFIG_EARLY_PRINTK. Fix
this by adding a delay. A successful reset disables the interrupt sources.
Also, after the reset for channel A setup, the SCC then gets a second
reset for channel B setup which leaves channel A uninitialised again. Fix
this by performing the reset only once.
