Merge tag 'loongarch-7.1' of git://git.kernel.org/pub/scm/linux/kernel/git/chenhuacai/linux-loongson
Pull LoongArch updates from Huacai Chen:
- Adjust build infrastructure for 32BIT/64BIT
- Add HIGHMEM (PKMAP and FIX_KMAP) support
- Show and handle CPU vulnerabilites correctly
- Batch the icache maintenance for jump_label
- Add more atomic instructions support for BPF JIT
- Add more features (e.g. fsession) support for BPF trampoline
- Some bug fixes and other small changes
