Geert Uytterhoeven 87d93029fe m68k: Fix asm register constraints for atomic ops 
Depending on register assignment by the compiler:

    {standard input}:3084: Error: operands mismatch -- statement `andl %a1,%d1' ignored
    {standard input}:3145: Error: operands mismatch -- statement `orl %a1,%d1' ignored
    {standard input}:3195: Error: operands mismatch -- statement `eorl %a1,%d1' ignored

Indeed, the first operand must not be an address register.  However, it
can be an immediate value.  Fix this by adjusting the register
constraint from "g" (general purpose register) to "di" (data register or
immediate).

Fixes: e39d88ea3c ("locking/atomic, arch/m68k: Implement atomic_fetch_{add,sub,and,or,xor}()")
Fixes: d839bae426 ("locking,arch,m68k: Fold atomic_ops")
Fixes: 1da177e4c3 ("Linux-2.6.12-rc2")

README 

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
