Subject: [PATCH] fbdev: section cleanup in efifb
Date: Fri, 18 Jun 2010 09:40:15 +0200

This patch removes 43 section mismatches by moving
the two structures efifb_defined and efifb_fix
from .init.data to .devinit.data.

Also the two structure arrays dmi_system_table[] and dmi_list[]
have been moved from .data to .init.rodata and .init.data,
which saves, if built-in, some space.

On x86_64 'size -A' showed that these sections changed size:

efifb.o:
section                     size-old        size-new
.data                       1200            688
.init.data                  7840            512
.init.rodata                0               7568
.devinit.data               0               256

Total                       11927           11911
