Looking into the patch, I wonder if the following is correct. -#if defined(CONFIG_CPU_MIPSR2) && !defined(CONFIG_CPU_CAVIUM_OCTEON) +#if defined(CONFIG_CPU_MIPSR2) || defined(CONFIG_CPU_MIPSR6) && !defined(CONFIG_CPU_CAVIUM_OCTEON) This change appears to be missing a ( ) around the first two defined() statements. Fixing that doesn't resolve the problem, though. Reverting the patch doesn't fix the problem either, so something else must be wrong. ----------------- Building mips:cavium_octeon_defconfig ... failed Error log: arch/mips/kernel/branch.c: In function '__compute_return_epc_for_insn': arch/mips/kernel/branch.c:785:2: error: duplicate case value arch/mips/kernel/branch.c:753:2: error: previously used here arch/mips/kernel/branch.c:808:2: error: duplicate case value arch/mips/kernel/branch.c:769:2: error: previously used here arch/mips/kernel/branch.c:818:2: error: duplicate case value arch/mips/kernel/branch.c:761:2: error: previously used here arch/mips/kernel/branch.c:826:2: error: duplicate case value arch/mips/kernel/branch.c:776:2: error: previously used here ---- Bisect points to commit 2f1da3620ff2 ("MIPS: Emulate the new MIPS R6 branch compact (BC) instruction"). Looking into the code, the patch quite obviously conflicts with cavium support. Guenter
