You may find that debugging with gdbstub or the qemu monitor easier with
a routine that walks page tables for loongarch_cpu_get_phys_page_debug.
For kvm, the existing code is insufficient anyway, because you'd need to
emulate a hardware page table walk, not use env->tlb[], which would not
be populated.
This can be improved later.
Sure, will add page table walk emulation code later in function
loongarch_cpu_get_phys_page_debug(). And thanks for your guidance.
