Message-Id: <1401981868-4108-1-git-send-email-shreyas@linux.vnet.ibm.com> Date: Thu, 5 Jun 2014 20:54:28 +0530 From: "Shreyas B. Prabhu" <shreyas@...ux.vnet.ibm.com> To: Benjamin Herrenschmidt <benh@...nel.crashing.org>, Paul Mackerras <paulus@...ba.org>, Michael Ellerman <mpe@...erman.id.au> Cc: linuxppc-dev@...ts.ozlabs.org, linux-kernel@...r.kernel.org, "Shreyas B. Prabhu" <shreyas@...ux.vnet.ibm.com> Subject: [PATCH 2/2] powerpc/powernv : Disable subcore for UP configs 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.c itself is relevant only on SMP and hence the better solution is to exclude subcore.c for UP builds. Signed-off-by: Shreyas B.
