Reply-to: ncunningham@users.sourceforge.net Message-id: <1074824487.12774.185.camel@laptop-linux> MIME-version: 1.0 Content-type: multipart/signed; boundary="=-xCMq03ux0VXVcqPq2vVF"; protocol="application/pgp-signature"; micalg=pgp-sha1 Sender: owner-linux-mm@kvack.org Return-Path: To: Linux Memory Management List-ID: --=-xCMq03ux0VXVcqPq2vVF Content-Type: text/plain Content-Transfer-Encoding: quoted-printable Hi. I guess the subject says it all, but I'll give more detail: I'm working on Suspend on a 8 cpu ("8 way"?) SMP box at OSDL, which has something in excess of 4GB, but I'm only using 4 at the moment: Warning only 4GB will be used. Use a PAE enabled kernel. 3200MB HIGHMEM available. 896MB LOWMEM available. When suspending, I am seeing pages that don't have the HighMem flag set, but for which page_address returns zero. I looked at kmap, and noticed that it tests for page < highmem_start_page; I guess this is the way to do it?
