Subject: [PATCH v2 2/2] MIPS: Loongson64: Define has_cpu_mips*r2_user for Loongson-3
Date: Thu, 22 Mar 2018 22:22:15 +0800 [thread overview]
Message-ID: <20180322142215.7705-2-jiaxun.yang@flygoat.com> (raw)
In-Reply-To: <20180322142215.7705-1-jiaxun.yang@flygoat.com>
All loongson-3 processors support mips32r2 mips64r2 usermode instructions.
However 3A1000 3B1000 3B1500 should be treated as r1 in kernel.
