[PATCH v2 0/3] Move thread_info into task_struct for LoongArch

[Tiezhu Yang]

Based on 7.1-rc7, tested with stress-ng, successfully passed
the 3-hours stress testing suite, UnixBench benchmarking shows
a steady performance lift across all core counts.

Thanks Huacai, Wang Rui, sashiko-bot and bot+bpf-ci for your
review comments and valuable suggestions.
