The error is fixed with the following patch that goes in before patch 3/6 above in the series. Let me know if I should post a v2 instead. Thanks, Deepa commit bfe4b046ed7f01154aef44fcb77d3f172929ccc2 Author: Deepa Dinamani <deepa.kernel@xxxxxxxxx> Date: Thu Jul 5 11:47:25 2018 -0700 riscv: Include asm-generic/compat.h riscv does not enable CONFIG_COMPAT in default configurations: defconfig, allmodconfig and nomodconfig. And hence does not inlude definitions for compat data types. Now that time syscalls are being reused in non CONFIG_COMPAT modes, include asm-generic definitions for riscv. Alternative would be to make compat_time.h to be conditional on CONFIG_COMPAT_32BIT_TIME. But, since riscv is already has an asm/compat.h include the generic version instead.
