sched/topology: Fix percpu data types in struct sd_data & struct s_data
The percpu members of struct sd_data and s_data are declared as: struct ... ** __percpu member; So their type is: __percpu pointer to pointer to struct ... But looking at how they're used, their type should be: pointer to __percpu pointer to struct ... and they should thus be declared as: struct ... * __percpu *member; So fix the placement of '__percpu' in the definition of these structures. This addresses a bunch of Sparse's warnings like: warning: incorrect type in initializer (different address spaces) expected void const [noderef] <asn:3> *__vpp_verify got struct sched_domain ** Signed-off-by: Luc Van Oostenryck <luc.vanoostenryck@gmail.com> Signed-off-by: Peter Zijlstra (Intel) <peterz@infradead.org> Cc: Linus Torvalds <torvalds@linux-foundation.org> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Thomas Gleixner <tglx@linutronix.de> Link: https://lkml.kernel.org/r/20190118144936.79158-1-luc.vanoostenryck@gmail.com Signed-off-by: Ingo Molnar <mingo@kernel.org>
