Subject: MIPS: Provide empty mips_mt_set_cpuoptions when CONFIG_MIPS_MT=n
X-Git-Tag: v3.15-rc1~125^2~10
X-Git-Url: https://asedeno.scripts.mit.edu/gitweb/?a=commitdiff_plain;h=d94c90f8050e1e7d46a4217909af106a08dd31ea;p=linux.git

MIPS: Provide empty mips_mt_set_cpuoptions when CONFIG_MIPS_MT=n

Both the CONFIG_MIPS_CPS & CONFIG_MIPS_CMP SMP implementations call
mips_mt_set_cpuoptions when preparing to start secondary CPUs. However
both may be used without MT. Provide an empty inline function to prevent
a link error in this case.
