Hi all, After merging the net-next tree, today's linux-next build (arm multi_v7_defconfig) failed like this: arm-linux-gnueabi-ld: drivers/net/ethernet/stmicro/stmmac/stmmac_tc.o: in function `tc_setup_taprio': stmmac_tc.c:(.text+0x4e8): undefined reference to `__aeabi_uldivmod' arm-linux-gnueabi-ld: stmmac_tc.c:(.text+0x508): undefined reference to `__aeabi_uldivmod' Caused by commit b60189e0392f ("net: stmmac: Integrate EST with TAPRIO scheduler API") I have used the net-nest tree from next-20191218 for today. -- Cheers, Stephen Rothwell
