Sorry for the empty warning here. The actual sparse warning is:

arch/x86/include/asm/processor.h:698:16: sparse: sparse: incorrect type in initializer (different address spaces)
arch/x86/include/asm/processor.h:698:16: sparse:     expected void const [noderef] __percpu *__vpp_verify
arch/x86/include/asm/processor.h:698:16: sparse:     got unsigned int *
