  selftests/bpf: Test jited inline of bpf_get_smp_processor_id() for LoongArch (2026-06-25 13:08:58 +0800)

----------------------------------------------------------------
LoongArch changes for v7.2

1, Add THREAD_INFO_IN_TASK implementation;
2, Add build salt to the vDSO;
3, Add some BPF JIT inline helpers;
4, Update DTS for I2C clocks and clock-frequency;
5, Some bug fixes and other small changes.

I'm sorry for the late Pull-Request because a 32BIT build error is
reported and fixed recently.
