4.19-stable review patch. If anyone has any objections, please let me know.
------------------
[ Upstream commit 99687cdbb3f6c8e32bcc7f37496e811f30460e48 ]
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 **
