level in kvm_mmu_page_role

I have been going through the kvm code but didn't get the significance of level in kvm_mmu_page_role. So, it would be nice if anyone can explain it what is its use?

Thanks,

It's the page table level. Level 1 contains page table entries pointing to 4k pages. Level 2 contains page directory entries pointing to level 1 page tables, or pointers to 2M pages, and so forth.
