From 1cdab55d8a8313f77a95fb8ca966dc4334f8e810 Mon Sep 17 00:00:00 2001 From: Benjamin Herrenschmidt Date: Sun, 22 Feb 2009 16:19:14 +0000 Subject: powerpc: Wire up /proc/vmallocinfo to our ioremap() This adds the necessary bits and pieces to powerpc implementation of ioremap to benefit from caller tracking in /proc/vmallocinfo, at least for ioremap's done after mem init as the older ones aren't tracked.
