From 4891645e764d2e181b834509a689fcd12e890c10 Mon Sep 17 00:00:00 2001 From: Jeremy Fitzhardinge Date: Wed, 30 Jan 2008 13:32:58 +0100 Subject: x86: unify paravirt pagetable accessors Put all the defines for mapping pagetable operations to their native versions (for the non-paravirt case) into one place. Make the corresponding changes to paravirt.h. The tricky part here is that when a pagetable entry can't be updated atomically (ie, 32-bit PAE), we need special handlers for pte_clear, set_pte_atomic and set_pte_present. However, the other two modes don't need special handling for these, and can use a common set_pte(_at) path.
