3.16.7-ckt19 -stable review patch. If anyone has any objections, please let me know. ------------------ From: Paul Burton <paul.burton@xxxxxxxxxx> commit 7a63076d9a31a6c2073da45021eeb4f89d2a8b56 upstream. The CONFIG_MIPS_MT symbol can be selected by CONFIG_MIPS_VPE_LOADER in addition to CONFIG_MIPS_MT_SMP. We only want MT code in the CPS SMP boot vector if we're using MT for SMP. Thus switch the config symbol we ifdef against to CONFIG_MIPS_MT_SMP.
