Hi,
Can this patchset be applied to linux-4.14.y. I've tried to build an arm kernel for these defconfigs:
mini2440_defconfig, mxs_defconfig, imx_v4_v5_defconfig, integrator_defconfig, lpc32xx_defconfig, s3c2410_defconfig, nhk8815_defconfig, imx_v6_v7_defconfig, at91_dt_defconfig, shmobile_defconfig, omap1_defconfig, multi_v5_defconfig, orion5x_defconfig, footbridge_defconfig, davinci_all_defconfig
Without this patchset these configs faild to build. Also I fixed a few warnings.
There are still a few more warnings to fix. But this is a start.
I built the kernel with tuxmake and this is the command: tuxmake --runtime podman --target-arch arm --toolchain clang-nightly --kconfig tinyconfig LLVM=1 LLVM_IAS=0
Similar results with clang-13.
