Subject: [PATCH AUTOSEL 4.19 012/167] KVM: x86: hyperv: consistently use 'hv_vcpu' for 'struct kvm_vcpu_hv' variables

From: Vitaly Kuznetsov <vkuznets@...hat.com>

[ Upstream commit 1779a39f786397760ae7a7cc03cf37697d8ae58d ]

Rename 'hv' to 'hv_vcpu' in kvm_hv_set_msr/kvm_hv_get_msr(); 'hv' is
'reserved' for 'struct kvm_hv' variables across the file.
