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 ---------------------------- Boards compiled: 50 Boards with errors: 6 ( M5253DEMO M54455EVB M54455EVB_a66 M54455EVB_i66 M54455EVB_intel M54455EVB_stm33 ) Boards with warnings but no errors: 44 ( M52277EVB M52277EVB_stmicro M5235EVB M5235EVB_Flash32 idmr cobra5272 eb_cpu5282 eb_cpu5282_internal TASREG M5208EVBE M5249EVB M5253EVBE M5271EVB M5272C3 M5275EVB M5282EVB astro_mcf5373l M53017EVB M5329AFEE M5329BFEE M5373EVB M54418TWR M54418TWR_nand_mii M54418TWR_nand_rmii M54418TWR_nand_rmii_lowfreq M54418TWR_serial_mii M54418TWR_serial_rmii M54451EVB M54451EVB_stmicro M5475AFE M5475BFE M5475CFE M5475DFE M5475EFE M5475FFE M5475GFE M5485AFE M5485BFE M5485CFE M5485DFE M5485EFE M5485FFE M5485GFE M5485HFE ) ----------------------------------------------------------
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.
