One comment about some of these vmlinux sizes. Due to the way the configs
are generated, the AM33xx data is being included into some of the kernels
that shouldn't have it. So for configs like omap3_4_testconfig or
omap2_4_testconfig, that AM33xx data accounts for about 12K of the 'data'
column that wasn't intended.
Kconfig handling in the scripts here needs some work; with luck, will
address that during this development cycle.
