From 5e5419734c8719cbc01af959ad9c0844002c0df5 Mon Sep 17 00:00:00 2001 From: Benjamin Herrenschmidt Date: Mon, 4 Feb 2008 22:29:14 -0800 Subject: add mm argument to pte/pmd/pud/pgd_free (with Martin Schwidefsky ) 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.
