Subject: [PATCH] MIPS: CPS: Guard mips_mt_set_cpuoptions call
Date: Thu, 18 Jun 2015 23:30:49 +0800	[thread overview]
Message-ID: <20150618232909-tung7970@googlemail.com> (raw)

Guard mips_mt_set_cpuoptions with MT specific options to
avoid undefined reference error on multicore platform
without multithreading support.
