Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/geert/linux-m68k

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/geert/linux-m68k:
  m68k: irq_node.handler() should return irqreturn_t
  m68k: section mismatch fixes: Atari SCSI
  m68k: section mismatch fixes: DMAsound for Atari
  MAINTAINERS: Replace dead link to m68k CVS repository by link to new git repository
  m68k: mac - Add SWIM floppy support
  m68k: mac - Add a new entry in mac_model to identify the floppy controller type.
  m68k: Add install target
