+{ + kvm_flush_remote_tlbs(kvm); +}FYI I also proposed a common kvm_flush_remote_tlbs() in my Common MMU series [1]. Could I interest you in grabbing patches 29-33 from that series, which has the same end result (common kvm_flush_remote_tlbs_range()) but also hooks up the KVM/x86 range-based flushing, and folding them into this series?

(Also they make kvm_arch_flush_remote_tlbs_memslot() common so you don't need the ARM-specific implementation in patch 4.)
