[ Upstream commit e5aff444e3a7bdeef5ea796a2099fc3c60a070fa ]
The sparse tool issues a warning for arch/x76/xen/enlighten_pv.c:
arch/x86/xen/enlighten_pv.c:120:9: sparse: sparse: incorrect type in initializer (different address spaces) expected void const [noderef] __percpu *__vpp_verify got bool *
This is due to the percpu variable xen_in_preemptible_hcall being exported via EXPORT_SYMBOL_GPL() instead of EXPORT_PER_CPU_SYMBOL_GPL().
