kvm_arch_flush_remote_tlbs() or CONFIG_HAVE_KVM_ARCH_TLB_FLUSH_ALL are two mechanisms to solve the same problem, allowing architecture-specific code to provide a non-IPI implementation of remote TLB flushing. Dropping CONFIG_HAVE_KVM_ARCH_TLB_FLUSH_ALL allows KVM to standardize all architectures on kvm_arch_flush_remote_tlbs() instead of maintaining two mechanisms.
