x86/cpu: Use EXPORT_PER_CPU_SYMBOL_GPL() for x86_spec_ctrl_current
Sparse rightfully complains:
bugs.c:71:9: sparse: warning: incorrect type in initializer (different address spaces)
bugs.c:71:9: sparse: expected void const [noderef] __percpu *__vpp_verify
bugs.c:71:9: sparse: got unsigned long long *
The reason is that x86_spec_ctrl_current which is a per CPU variable is
exported with EXPORT_SYMBOL_GPL().
Use EXPORT_PER_CPU_SYMBOL_GPL() instead.
