Unfortunately, that branch doesn't build for arm64 because of Nick's patch
moving tlb_flush_mmu_tlbonly() into tlb.h (which I acked!). It's a static
inline which calls tlb_flush(), which in our case is also a static inline
but one that is defined in our asm/tlb.h after including asm-generic/tlb.h.

Ah, just noticed you've pushed this to master! Please could you take the
arm64 patch below on top, in order to fix the build?

Cheers,

Will
