This series is based on the latest bpf-next tree.

I can not test the patch #1 on riscv due to no riscv machine, I only
tested the patch #2 with the same change on LoongArch based on the RFC
"LoongArch: Implement CONFIG_THREAD_INFO_IN_TASK" [1], it works well.

I think the patch #1 is right for riscv in theory, because it supports
CONFIG_THREAD_INFO_IN_TASK and there is member preempt_count in struct
thread_info. I hope someone from riscv side can help test this patch.
If no, I will try to test. Thanks in advance.
