linux-next: build failure after merge of the final tree (akpm-current tree related)

Hi all,

After merging the final tree, today's linux-next build (arm defconfig)
failed like this:

arch/arm/kernel/built-in.o: In function `parse_tag_ramdisk':
io.c:(.init.text+0xc4c): undefined reference to `rd_size'

Caused by commit bf27a0131289 ("drivers/block/brd.c: make 'rd_size'
static") from the akpm-current tree.

I have reverted that commit for today.
