From: Benjamin Herrenschmidt <[email protected]>
From: Martin Schwidefsky <[email protected]>
The pgd/pud/pmd/pte page table allocation functions get a mm_struct
pointer as first argument. The free functions do not get the mm_struct
argument. This is 1) asymmetrical and 2) to do mm related page table
allocations the mm argument is needed on the free function as well.
