[PATCH v2 3/7] KVM: x86: Move kvm_ops_static_call_update() to x86.c

From: Like Xu
Date: Mon Nov 08 2021 - 06:11:00 EST


From: Like Xu <likexu@xxxxxxxxxxx>

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.
