Date: Wed, 5 Aug 2015 15:42:39 -0700 From: Paul Burton <paul.burton@...tec.com> To: <linux-mips@...ux-mips.org> CC: Paul Burton <paul.burton@...tec.com>, Markos Chandras <markos.chandras@...tec.com>, <stable@...r.kernel.org>, Ralf Baechle <ralf@...ux-mips.org>, <linux-kernel@...r.kernel.org> Subject: [PATCH 5/6] MIPS: CONFIG_MIPS_MT_SMP should depend upon CPU_MIPSR2 The MT ASE cannot be used with CPUs that implement older releases of the MIPS architecture than release 2, and is replaced in release 6. Encode these constraints in Kconfig to ensure that MT code is only built as part of kernels targeting an appropriate revision of the architecture.
