Sorry to confuse your. I get from CCers from get_maintainer.pl script. The next patch "[PATCH V4 3/15]KVM: Replace old tlb flush function with new one to flush a specified range" calls new function. https://lkml.org/lkml/2018/10/13/254 The patch "[PATCH V4 4/15] KVM: Make kvm_set_spte_hva() return int" changes under ARM directory. Please have a look.
