Issue 465: Problem with framebuffer memory allocation

Reported by Nikolaus Schaller, Jul 28, 2013

The 3.10 (or 3.11) kernel needs to be configured with

CONFIG_FORCE_MAX_ZONEORDER=12

which itself needs a patch to arch/arm/Kconfig

Otherwise it will complain about

[    3.106109] OMAPFB: allocating 8388608 bytes for fb 0

The interesting thing is that this was NOT a problem on the 3.7 
kernel, and it appears only if we do NOT configure for 
CONFIG_CMDLINE_EXTEND.

So this error is triggered by some bootargs setting coming from 
U-Boot. But as said the same was NOT a problem on the 3.7 kernel.

This bug needs some research to better understand the real cause and 
the current modification of  arch/arm/Kconfig is just a work-around.
