size in terms of lines (instead of bytes). When changing video mode in ioctl SW_XXX commands, syscons checks scp->history_size and allocate a history buffer at least as large as the new screen size. (This was unnecessary before, because HISTORY_SIZE was as large as 100 lines and this is bigger than the maximum screen size: 60 lines). Similar adjustment is done in ioctl CONS_HISTORY command too.
