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

Pull m68k updates from Geert Uytterhoeven:
"Highlights:
- support for running kernels in fast TT-RAM instead of slow ST-RAM
on Atari
- multi-platform EARLY_PRINTK
- better support for machines with lots of RAM (think ARAnyM), and
for running kernels larger than 4 MiB (think multi-platform)"

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/geert/linux-m68k:
m68k/hp300: Convert printk to pr_foo()

m68k: Update defconfigs for v3.15-rc2
m68k/atari: fix SCC initialization for debug console
m68k/mvme16x: Adopt common boot console
m68k: Multi-platform EARLY_PRINTK
m68k: Toward platform agnostic framebuffer debug logging
m68k/atari - atari_scsi: use correct virt/phys translation for DMA buffer
m68k/atari - ataflop: use correct virt/phys translation for DMA buffer
m68k/atari - atafb: convert allocation of fb ram to new interface
m68k/atari - stram: alloc ST-RAM pool even if kernel not in ST-RAM

           Write kernel log output directly to a serial port.
+          Where implemented, output goes to the framebuffer as well.
+          PROM console functionality on Sun 3x is not affected by this option.
+
+          Pass "earlyprintk" on the kernel command line to get a
+          boot console.
 
           This is useful for kernel debugging when your machine crashes very
-          early before the console code is initialized.
+          early, i.e. before the normal console driver is loaded.
           You should normally say N here, unless you want to debug such a crash.
