Does TLB save level-1 page directory entries?

Note: This was originally posted on 18th March 2009 at http://forums.arm.com

Hi All,
In ARM1176, does TLB save level-1 page directory entries? I know that section's descriptor is saved in level-1 page table and TLB saves section's descriptor. Besides section's descriptor, there are page directory entries in level-1 page table, which is used to point to level-2 page tables. So, my question is: does TLB save level-1 page directory entries? Can anybody clarify the question for me? Thanks in advance.
