SubjectRe: [PATCH 3/6] timex: prepare compat helpers for y2038 changes
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

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.
