From 5cbf968803ae049f501cedf87b99ee60c786c451 Mon Sep 17 00:00:00 2001 From: Paul Burton Date: Mon, 7 Aug 2017 16:01:16 -0700 Subject: MIPS: Make CONFIG_MIPS_MT_SMP default y On systems that support MT ASE multithreading (ie. VPEs) we are very likely to want to include that support as default. Rather than setting it in various defconfigs, simply make CONFIG_MIPS_MT_SMP default y such that systems which select CONFIG_SYS_SUPPORTS_MULTITHREADING get it by default. As well as allowing us to remove the selection of CONFIG_MIPS_MT_SMP from various defconfigs, this also allows the generated generic defconfigs which derive from generic_defconfig to automatically gain support for MT ASE SMP when building for a suitable (pre-MIPSr6) ISA. For malta_kvm_guest_defconfig CONFIG_MIPS_MT_SMP is explicitly disabled since enabling SMP implicitly disables CONFIG_KVM_GUEST, which depends on CONFIG_BROKEN_ON_SMP.
