    Subject[PATCH v7 03/12] KVM: Remove CONFIG_HAVE_KVM_ARCH_TLB_FLUSH_ALL
    From
    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.
