From 7d907fa1c6ccb64c7f64cc7d3dcc7f6fe30a67b4 Mon Sep 17 00:00:00 2001 From: James Hogan Date: Fri, 4 Jul 2014 11:59:46 +0100 Subject: MIPS: smp-mt: Fix link error when PROC_FS=n Commit d6d3c9afaab4 (MIPS: MT: proc: Add support for printing VPE and TC ids) causes a link error when CONFIG_PROC_FS=n: arch/mips/built-in.o: In function `proc_cpuinfo_notifier_init': smp-mt.c: undefined reference to `register_proc_cpuinfo_notifier' This is fixed by adding an ifdef around the procfs handling code in smp-mt.c.
