Hello.
Even after applying the patch
"config.mk: fix -fstack-usage support test"
(http://patchwork.ozlabs.org/patch/283619/),
I still cannot compile m68k correctly.
The result of `CROSS_COMPILE=m68k-linux- ./MAKEALL -a m68k` is
--------------------- SUMMARY ----------------------------

I just took a look and
I found lots of files are left broken for a long term.
I pick up some them here.

I began to fix some of them and I gave up on the way.
Who is the custodian of M68K?
I doubt M68K is maintained.
Masahiro Yamada (3):
i2c: eliminate warnings in i2c_reloc_fixup function
m68k: eliminate warnings in do_bootm_linux function
m68k: eliminate a warning in cpu_init
