Subject: [PATCH v3 2/3] MIPS: microMIPS: Add kernel_uses_mmips in cpu-features.h
Date: Mon, 27 May 2013 19:01:02 +0800 [thread overview]
Message-ID: <20130527110102.GC31548@hades> (raw)
In-Reply-To: <20130527105810.GA31548@hades>
Add kernel_uses_mmips to denote whether CONFIG_CPU_MICROMIPS
is set or not. This variable can help cut down #ifdef usage.
