Subject: arm/arm64: KVM: arch_timer: Initialize cntvoff at kvm_init
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=a1a64387adeeba7a34ce06f2774e81f496ee803b;p=openwrt%2Fstaging%2Fblogic.git

arm/arm64: KVM: arch_timer: Initialize cntvoff at kvm_init

Initialize the cntvoff at kvm_init_vm time, not before running the VCPUs
at the first time because that will overwrite any potentially restored
values from user space.
