* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/geert/linux-m68k:
  m68k: Fix assembler constraint to prevent overeager gcc optimisation
  mac_esp: rename irq
  mac_scsi: dont enable mac_scsi irq before requesting it
  macfb: fix black and white modes
  m68k/irq: Remove obsolete IRQ_FLG_* definitions

Fix up trivial conflict in arch/m68k/kernel/process_mm.c as per Geert.
