From 93df766322ba1db2801e4b826985a4932dd75866 Mon Sep 17 00:00:00 2001 From: Avi Kivity Date: Fri, 2 May 2008 13:23:10 +0300 Subject: [PATCH] KVM: MMU: Allow more than PAGES_PER_HPAGE write protections per large page nonpae guests can call rmap_write_protect twice per page (for page tables) or four times per page (for page directories), triggering a bogus warning.
