Subject: linux-next: build warning after merge of the mm tree

Hi all,

After merging the mm tree, today's linux-next build (powerpc allnoconfig,
powerpc ppc44x_defconfig and arm64 defconfig) produced this warning:

WARNING: unmet direct dependencies detected for ARCH_ENABLE_MEMORY_HOTREMOVE
  Depends on [n]: MEMORY_HOTPLUG [=n]
  Selected by [y]:
  - PPC [=y]
Building: powerpc64 allnoconfig

WARNING: unmet direct dependencies detected for ARCH_ENABLE_MEMORY_HOTREMOVE
  Depends on [n]: MEMORY_HOTPLUG [=n]

Probably introduced by commit
