Subject: [patch 1/3] add mm argument to pte/pmd/pud/pgd_free.
Date: Mon, 12 Nov 2007 15:30:10 +0100	[thread overview]
Message-ID: <20071112144009.610884254@de.ibm.com> (raw)
In-Reply-To: <20071112143009.425807965@de.ibm.com>

[-- Attachment #1: 001-mm-pxdfree.diff --]
[-- Type: text/plain, Size: 46686 bytes --]

From: Benjamin Herrenschmidt <benh@kernel.crashing.org>
From: Martin Schwidefsky <schwidefsky@de.ibm.com>

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.
