Unregister the driver before removing multi-instance hotplug callbacks. This order avoids the warning issued from __cpuhp_remove_state_cpuslocked when the number of remaining instances isn't yet zero.

Both call sites, that access kmmio_ctx, access kmmio_ctx with interrupts disabled. There is no need to use get_cpu_var() which additionally disables preemption. Use this_cpu_ptr() to access the kmmio_ctx variable of the current CPU.

Install the callbacks via the state machine. The driver supports multiple instances and therefore the new cpuhp_state_add_instance_nocalls() infrastrucure is used. The driver currently uses get_online_cpus() to avoid missing a CPU hotplug event while invoking virtnet_set_affinity(). This could be avoided by using cpuhp_state_add_instance() variant which holds the hotplug lock and invokes callback

From: Borislav Petkov <bp at suse.de> Using static_cpu_has() is pointless on those paths, convert them to the boot_cpu_has() variant. No functional changes.
