[PATCH v1 0/3] Move thread_info into task_struct for LoongArch

[Tiezhu Yang]

This is a formal patch series, based on 7.1-rc7, addressed all
the review comments, tested with stress-ng, successfully passed
the 3-hours stress testing suite.

stress-ng --context $(nproc) --timeout 30m --metrics-brief
stress-ng --sysbadaddr $(nproc) --timeout 30m
stress-ng --fault $(nproc) --timeout 30m
stress-ng --pthread $(nproc) --timeout 30m
stress-ng --schedmix $(nproc) --yield $(nproc) --timeout 60m --metrics

Additionally, UnixBench benchmarking shows a steady performance
lift across all core counts.
