I think this is the cause of some kernelci failures in current linux-next builds: https://kernelci.org/build/next/branch/master/kernel/next-20190702/ bigsur_defconfig ‐ mips3 warnings — 1 error cavium_octeon_defconfig ‐ mips3 warnings — 1 error ip27_defconfig ‐ mips3 warnings — 1 error loongson3_defconfig ‐ mips3 warnings — 1 error mips_paravirt_defconfig ‐ mips3 warnings — 1 error nlm_xlp_defconfig ‐ mips3 warnings — 1 error nlm_xlr_defconfig ‐ mips1 warning — 1 error /home/buildslave/workspace/workspace/kernel-build@8/linux/build/../kernel/dma/direct.c:144: undefined reference to `arch_dma_prep_coherent' 2/home/buildslave/workspace/kernel-build/linux/build/../kernel/dma/direct.c:144: undefined reference to `arch_dma_prep_coherent' 2(.text+0xafc): undefined reference to `arch_dma_prep_coherent' 1direct.c:(.text+0x934): undefined reference to `arch_dma_prep_coherent' 1(.text+0xb84): undefined reference to `arch_dma_prep_coherent' I haven't looked into the details, but I suspect all machines with cache-coherent DMA are broken.
