[PATCHES] Ubuntu trivial powerpc patches

[PATCHES] Ubuntu trivial powerpc patches

[Ben Collins]

Here's a couple of small patches I've got in the Ubuntu kernel tree for
powerpc. They can be synced from:

git.kernel.org:/pub/scm/linux/kernel/git/bcollins/ubuntu-2.6#ubuntu-powerpc

The patch for prom init printf's disabling is just to make the boot a
little cleaner.

Ben Collins:
      [powerpc] Allow disabling of prom init messages.
      [powerpc] Make pSeries_init_panel message configurable.

The help text should probably be a little bit less cryptic :) Something
like saying that those messages are displayed by the Open Firmware
wrapper.
