Subject: linux-next: build failure after merge of the akpm-current tree

After merging the akpm-current tree, today's linux-next build (powerpc
ppc44x_defconfig) failed like this:

Caused by commit

  a6d52df2d8bc ("zram: break the strict dependency from lzo")

I have reverted that commit for today.
