The with_address() variant is statically defined in mmu.c, arguably kvm_arch_flush_remote_tlbs_memslot() belongs in mmu.c anyways, and defining kvm_arch_flush_remote_tlbs_memslot() in mmu.c will allow the compiler to inline said function when a future patch consolidates open coded variants of the function. No functional change intended.
