Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/geert/linux-m68k
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. * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/geert/linux-m68k: 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 m68k: switch to using the asm-generic hw_irq.h arch/m68k: remove CONFIG_EXPERIMENTAL
