Subject[PATCH v3 1/4] KVM: x86: Move kvm_ops_static_call_update() to x86.c
Date
From: Like Xu <likexu@tencent.com>

The kvm_ops_static_call_update() is defined in kvm_host.h. That's
completely unnecessary, it should have exactly one caller,
kvm_arch_hardware_setup(). As a prep match, move
kvm_ops_static_call_update() to x86.c, then it can reference
the kvm_pmu_ops stuff.
