[PATCH 12 of 13] Pass the mm struct into the pgd_free code so the mm is available here

[ak at suse.de (Andi Kleen)]

nst char *arch_vma_name(struct vm_area_struct *vma);

Sorry, but these ifdefs are too ugly. I would prefer if you 
just updated all architectures, even though it will make the patch
somewhat bigger
