From cbd717585b8038d93c309176bb563a5c6de60ac7 Mon Sep 17 00:00:00 2001 From: Wei Wang Date: Fri, 29 May 2020 15:43:44 +0800 Subject: KVM: x86/pmu: Tweak kvm_pmu_get_msr to pass 'struct msr_data' in Change kvm_pmu_get_msr() to get the msr_data struct, as the host_initiated field from the struct could be used by get_msr. This also makes this API consistent with kvm_pmu_set_msr. No functional changes.
