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

Hi Andrew,

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

mm/built-in.o: In function `shrink_slab.part.73.constprop.83':
vmscan.c:(.text+0xf760): undefined reference to `__srcu_read_lock'
vmscan.c:(.text+0xf924): undefined reference to `__srcu_read_unlock'
mm/built-in.o: In function `unregister_shrinker':
(.text+0xfa60): undefined reference to `synchronize_srcu'
mm/built-in.o:(.data+0x1e8): undefined reference to `process_srcu'

Caused by commit

  dab937da82f9 ("mm: srcu-ify shrinkers")

I have reverted that commit for today.
