Yep that fixes it.  Patch below (for stable 3.2 only)

Subject: powerpc/eeh: Fix compile error due to missing include file

3.2.40 fails to compile the celleb_defconfig with the following error:

  arch/powerpc/kernel/of_platform.c: In function 'of_pci_phb_probe':
  arch/powerpc/kernel/of_platform.c:95:2: error: implicit declaration of function 'eeh_add_sysfs_files' [-Werror=implicit-function-declaration]

The following adds the required include file to fix this.
