Just to let you know, due to upstream code madness ppc does not actually
use the define in the ppc headers but uses the common generic default.
This likely needs to become a configurable.  In the sort term I have
switch the patch to the below, moving the default up to 2048.  This
moves it to 2048 for all architectures using the default, arm has its
own 1024 override, and x86 overrides it to 2048 already.  So this should
have the same effect.

Joe is owning getting some sanity for this upstream.

Subject: [PATCH] UBUNTU: SAUCE: (no-up) powerpc: Increase COMMAND_LINE_SIZE to
 2048 from 512.

BugLink: http://bugs.launchpad.net/bugs/1306677

Powerpc currently does not actually use its own define, but instead
uses the common unconfigurable define.  We should be able to configure
this per architecture, but we cannot.
