Pull m68k updates from Geert Uytterhoeven.

Fix up trivial conflict (m68k switched to generic version of
uapi/asm/socket.h, net tree updated the old one) as per Geert.

  m68k/sun3: Fix instruction faults
  m68k/sun3: Get interrupts working again
  m68k: move to a single instance of free_initmem()
  m68k: merge MMU and non-MMU versions of mm/init.c
  m68k: switch to using the asm-generic termios.h
  m68k: switch to using the asm-generic termbits.h
  m68k: switch to using the asm-generic sockios.h
  m68k: switch to using the asm-generic socket.h
  m68k: switch to using the asm-generic shmbuf.h
  m68k: switch to using the asm-generic sembuf.h
  m68k: switch to using the asm-generic msgbuf.h
  m68k: switch to using the asm-generic auxvec.h
  m68k: switch to using the asm-generic shmparam.h
  m68k: switch to using the asm-generic spinlock.h
