From 9b48b46678989b67cd00658ea88964163eaab616 Mon Sep 17 00:00:00 2001 From: Dean Nelson Date: Tue, 22 Mar 2005 16:00:00 -0700 Subject: [IA64-SGI] move nodepda pointer out of pda Remove the p_nodepda and p_subnodepda pointers from the pda_s structure. And then define a new per-cpu pointer to the nodepda and export it so that it can be accessed by kernel modules.
