Hi Andrew, After merging the akpm-current tree, today's linux-next build (x86 allmodconfig) failed like this: CC [M] drivers/net/ethernet/netronome/nfp/nfp_app.o In file included from /home/broonie/tmpfs/next/drivers/net/ethernet/netronome/nfp/nfp_asm.c:40:0: /home/broonie/tmpfs/next/drivers/net/ethernet/netronome/nfp/nfp_asm.h: In function '__enc_swreg_lm': /home/broonie/tmpfs/next/drivers/net/ethernet/netronome/nfp/nfp_asm.h:301:2: error: implicit declaration of function 'WARN_ON' [-Werror=implicit-function-declaration] WARN_ON(id > 3 || (off && mode != NN_LM_MOD_NONE)); ^ cc1: some warnings being treated as errors Caused by some reliance on an implicit include being exposed by a header reorganization in your tree. I'll add a patch for this which I'll post, probably tomorrow morning.
