[PATCH] constify and annotate __read_mostly in vgacon.c and fbmem.c
- annotate some variables from vgacon.c and fbmem.c as __read_mostly - move the mask[] array in fb_set_logo_truepalette() into the .rodata section Signed-off-by: Helge Deller <deller@gmx.de> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
