From 7a50e4688dabb8005df39b2b992d76629b8af8aa Mon Sep 17 00:00:00 2001 From: Hauke Mehrtens Date: Sun, 6 Mar 2016 22:28:56 +0100 Subject: [PATCH] MIPS: Fix build error when SMP is used without GIC The MIPS_GIC_IPI should only be selected when MIPS_GIC is also selected, otherwise it results in a compile error. smp-gic.c uses some functions from include/linux/irqchip/mips-gic.h like plat_ipi_call_int_xlate() which are only added to the header file when MIPS_GIC is set. The Lantiq SoC does not use the GIC, but supports SMP. The calls top the functions from smp-gic.c are already protected by some #ifdefs The first part of this was introduced in commit 72e20142b2bf ("MIPS: Move GIC IPI functions out of smp-cmp.c") Signed-off-by: Hauke Mehrtens Cc: Paul Burton Cc: stable@vger.kernel.org # v3.15+ Cc: linux-mips@linux-mips.org Patchwork: https://patchwork.linux-mips.org/patch/12774/ Signed-off-by: Ralf Baechle --- arch/mips/Kconfig | 7 ++++--- 1 file changed, 4 insertions(+), 3 deletions(-) diff --git a/arch/mips/Kconfig b/arch/mips/Kconfig index 74a3db92da1b..d3da79dda629 100644 --- a/arch/mips/Kconfig +++ b/arch/mips/Kconfig @@ -2169,7 +2169,7 @@ config MIPS_MT_SMP select CPU_MIPSR2_IRQ_VI select CPU_MIPSR2_IRQ_EI select SYNC_R4K - select MIPS_GIC_IPI + select MIPS_GIC_IPI if MIPS_GIC select MIPS_MT select SMP select SMP_UP @@ -2267,7 +2267,7 @@ config MIPS_VPE_APSP_API_MT config MIPS_CMP bool "MIPS CMP framework support (DEPRECATED)" depends on SYS_SUPPORTS_MIPS_CMP && !CPU_MIPSR6 - select MIPS_GIC_IPI + select MIPS_GIC_IPI if MIPS_GIC select SMP select SYNC_R4K select SYS_SUPPORTS_SMP @@ -2287,7 +2287,7 @@ config MIPS_CPS select MIPS_CM select MIPS_CPC select MIPS_CPS_PM if HOTPLUG_CPU - select MIPS_GIC_IPI + select MIPS_GIC_IPI if MIPS_GIC select SMP select SYNC_R4K if (CEVT_R4K || CSRC_R4K) select SYS_SUPPORTS_HOTPLUG_CPU @@ -2306,6 +2306,7 @@ config MIPS_CPS_PM bool config MIPS_GIC_IPI + depends on MIPS_GIC bool config MIPS_CM -- 2.20.1
