/local/tbogendoerfer/korg/linux/mm/memory.c: In function ‘set_pte_range’:
/local/tbogendoerfer/korg/linux/mm/memory.c:4290:2: error: implicit declaration of function ‘update_mmu_cache_range’ [-Werror=implicit-function-declaration]
  update_mmu_cache_range(vma, addr, vmf->pte, nr);

update_mmu_cache_range() is missing in this patch.
