From: Michael Ellerman Date: Thu, 8 Mar 2018 02:54:39 +0000 (+1100) Subject: powerpc/pseries: Move smp_query_cpu_stopped() etc. out of plpar_wrappers.h X-Git-Tag: v5.15~9084^2~134 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=16560e88320d276036b393d4ba51cf0184f6caca;p=platform%2Fkernel%2Flinux-starfive.git powerpc/pseries: Move smp_query_cpu_stopped() etc. out of plpar_wrappers.h smp_query_cpu_stopped() and related #defines are currently in plpar_wrappers.h. The function actually does an RTAS call, not an hcall, and basically has nothing to do with plpar_wrappers.h Move it into pseries.h, where it can easily be used by the only two callers in pseries/smp.c and pseries/hotplug-cpu.c.
