smpboot: Place the __percpu annotation correctly
[ Upstream commitd4645d30b5
] The test robot reported a wrong assignment of a per-CPU variable which it detected by using sparse and sent a report. The assignment itself is correct. The annotation for sparse was wrong and hence the report. The first pointer is a "normal" pointer and points to the per-CPU memory area. That means that the __percpu annotation has to be moved. Move the __percpu annotation to pointer which points to the per-CPU area. This change affects only the sparse tool (and is ignored by the compiler).
