Today's linux-next fails to build an arm64 allnoconfig due to "mm: make GUP handle pfn mapping unless FOLL_GET is requested" which causes:
arm64-allnoconfig ../mm/gup.c:51:4: error: implicit declaration of function 'update_mmu_cache' [-Werror=implicit-function-declaration]
The update_mmu_cache() function is defined unconditionally in asm/tlbflush.h so there is presumably some path of conditional inclusions which causes it not to get declared in an allnoconfig - I didn't chase that down yet.
Maybe we should move it to asm/pgtable.h like many other architectures.
