Message-Id: <20070807071955.7E419DDE05@ozlabs.org>
Date: Tue, 07 Aug 2007 17:19:49 +1000
From: Benjamin Herrenschmidt <benh@...nel.crashing.org>
To: Linux Memory Management <linux-mm@...ck.org>
CC: <linux-kernel@...r.kernel.org>
Subject: [RFC/PATCH 5/12] Add mm argument to pte/pmd/pud/pgd_free.
Based on a patch from: Martin Schwidefsky <schwidefsky@...ibm.com>
pte_alloc_one/pte_alloc_one_kernel get the mm as argument. If the page
table allocation depends on the mm pte/pmd/pud/pgd_free should get
the mm argument as well. That way it will be possible to have per-mm
lists of page table pages. I haven't changed pte_free_kernel at this
stage though.
