I can reproduce this error with the configuration that the bot provides at both 4483397b03536506535d611b0cb28a81a69e8edf and v5.17-rc3, even with GCC: $ curl -LSso .config https://download.01.org/0day-ci/archive/20220205/202202050539.Mtk9I4Ef-lk... $ make -skj"$(nproc)" ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- olddefconfig all ... arm-linux-gnueabi-ld: arch/arm/mach-socfpga/socfpga.o: in function `socfpga_init_irq': socfpga.c:(.init.text+0x104): undefined reference to `socfpga_reset_init' ... Whether or not this reproduces with the in-tree socfpga_defconfig, I am not sure.
