Hi All, The latest mainline kernel branch fails to build for mips allmodconfig with the error: drivers/net/wireless/intel/iwlwifi/pcie/trans.c:1093: error: "CAUSE" redefined [-Werror] 1093 | #define CAUSE(reg, mask) \ | In file included from ./arch/mips/include/asm/ptrace.h:19, from ./include/linux/sched/signal.h:14, from ./include/linux/rcuwait.h:6, from ./include/linux/percpu-rwsem.h:7, from ./include/linux/fs.h:33, from ./arch/mips/include/asm/elf.h:12, from ./include/linux/elf.h:6, from ./include/linux/module.h:19, from ./include/linux/device/driver.h:21, from ./include/linux/device.h:32, from ./include/linux/pci.h:37, from drivers/net/wireless/intel/iwlwifi/pcie/trans.c:7: ./arch/mips/include/uapi/asm/ptrace.h:18: note: this is the location of the previous definition 18 | #define CAUSE 65 git bisect pointed to c1918196427b ("iwlwifi: pcie: simplify MSI-X cause mapping") And, reverting it on top of mainline branch has fixed the build failure. -- Regards Sudip
