FWIW the error in question is:

It was introduced by 3f8cb098859bbea29d7b3765a3102e4a6bf81b85
(drivers/net/lib8390: fix warning, trim trailing whitespace)

The problem is that ei_inb_p() is using various #defines (from
drivers/net/8390.h) that use EI_SHIFT, which in the zorro8390 case uses
ei_local.  Since zorro8390 is only build for m68k, guard the definition of
ei_local with CONFIG_M68K

The patch below fixes the zorro8390 build, and I think will keep the warnings
that Jeff is trying to silence silenced.
