[PATCH v3 0/3] m68k: Bug fix and cleanup for framebuffer debug console

[Finn Thain <fthain@linux-m68k.org>]

This series has a bug fix for the early bootconsole as well as some
related efficiency improvements and cleanup.

The relevant code is subject to CONSOLE_DEBUG, which is presently only
used with CONFIG_MAC. To test this series (in qemu-system-m68k, for example)
it's helpful to enable CONFIG_EARLY_PRINTK and
CONFIG_FRAMEBUFFER_CONSOLE_DEFERRED_TAKEOVER and boot with
kernel parameters 'console=ttyS0 earlyprintk keep_bootcon'.

  m68k: Fix lost column on framebuffer debug console

  m68k: Remove unused "cursor home" code from debug console
