Use {ERR_PTR,IS_ERR,PTR_ERR}_PCPU() macros when crossing between generic and percpu address spaces and add __percpu annotation to *stats pointer to fix percpu address space issues. NOTE: The patch depends on a patch that introduces *_PCPU() macros [1] that is on the way to mainline through the mm tree. For convience, the patch is included in this patch series, so CI tester is able to test the second patch without compile failures.
