From ad417330628c60e83692211e7161eb49e1843318 Mon Sep 17 00:00:00 2001 From: "Shreyas B. Prabhu" Date: Fri, 6 Jun 2014 15:52:51 +0530 Subject: [PATCH] powerpc/powernv : Disable subcore for UP configs MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Build throws following errors when CONFIG_SMP=n arch/powerpc/platforms/powernv/subcore.c: In function ‘cpu_update_split_mode’: arch/powerpc/platforms/powernv/subcore.c:274:15: error: ‘setup_max_cpus’ undeclared (first use in this function) arch/powerpc/platforms/powernv/subcore.c:285:5: error: lvalue required as left operand of assignment 'setup_max_cpus' variable is relevant only on SMP, so there is no point working around it for UP. Furthermore, subcore itself is relevant only on SMP and hence the better solution is to exclude subcore.o and subcore-asm.o for UP builds. Signed-off-by: Shreyas B. Prabhu Reviewed-by: Srivatsa S.
