This breaks m68k/allmodconfig:

drivers/net/ethernet/freescale/gianfar.c: In function ‘gfar_parse_group’:
drivers/net/ethernet/freescale/gianfar.c:684: error: ‘NO_IRQ’
undeclared (first use in this function)
drivers/net/ethernet/freescale/gianfar.c:684: error: (Each undeclared
identifier is reported only once
drivers/net/ethernet/freescale/gianfar.c:684: error: for each function
it appears in.)

P.S. Hint: Would have been caught earlier if the NET_VENDOR_* symbol
     had "|| COMPILE_TEST" among its dependencies.
