Include percpu.h to pick up the definition of DECLARE_PER_CPU() and
friends instead of relying on the parent to provide the #include. E.g.
swapping the order of includes in arch/x86/kvm/vmx/nested.c (simulating
KVM code movement being done for other purposes) results in build errors:
In file included from arch/x86/kvm/vmx/nested.c:3:
