The percpu member of this structure is declared as:
struct ... ** __percpu member;
So its type is:
__percpu pointer to pointer to struct ...
But looking at how it's used, its type should be:
pointer to __percpu pointer to struct ...
and it should thus be declared as:
struct ... * __percpu *member;
So fix the placement of '__percpu' in the definition of this
structures.
This silents a few Sparse's warnings like:
warning: incorrect type in initializer (different address spaces)
expected void const [noderef] <asn:3> *__vpp_verify
got struct sched_domain **
