  swim: Release memory region after incorrect return/goto
  m68k/irq: Vector ints need a valid interrupt handler
  m68k/math-emu: unsigned issue, 'unsigned long' will never be less than zero
  m68k: remove CONFIG_EARLY_PRINTK dependency on CONFIG_EMBEDDED, default to n
  m68k/sun3: remove inline marking of EXPORT_SYMBOL functions
  [SCSI] a3000: use module_platform_driver_probe()
