If anyone has any objections, please let me know. ------------------ From: James Hogan commit 7d907fa1c6ccb64c7f64cc7d3dcc7f6fe30a67b4 upstream. 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.
