Loongson-3A6000 and newer processors have hardware page table walker
(PTW) support. PTW can handle all fastpaths of PIL/PIS/PIF/PIE
exceptions by hardware.
V2:
- Remove the '21' magic value, patch1;
- Add a flag is_debug for debug access, patch5;
- Use qatomic_cmpxchg to change the new pte_val, patch5.
