Hi Josh,

After merging the tiny tree, today's linux-next build (powerpc
ppc64_defconfig) failed like this:

mm/built-in.o: In function `.isolate_migratepages_range':
(.text+0x2fbd8): undefined reference to `.balloon_page_isolate'
mm/built-in.o: In function `.putback_movable_pages':
(.text+0x713c4): undefined reference to `.balloon_page_putback'
mm/built-in.o: In function `.migrate_pages':
(.text+0x72a00): undefined reference to `.balloon_page_migrate'

Caused by commit b37a3fee8450 ("mm: Disable mm/balloon_compaction.c
completely when !CONFIG_VIRTIO_BALLOON").

I have reverted that commit for today.
