[PATCH v3 6/8] x86/reboot: Unconditionally define cpu_emergency_virt_cb typedef

From: Sean Christopherson
Date: Fri Jun 07 2024 - 20:08:37 EST


Define cpu_emergency_virt_cb even if the kernel is being built without KVM
support so that KVM can reference the typedef in asm/kvm_host.h without
needing yet more #ifdefs.

No functional change intended.
