From 5b7e0102ae744e9175b905f4267a81393bdb7a75 Mon Sep 17 00:00:00 2001 From: Avi Kivity Date: Wed, 14 Apr 2010 19:20:03 +0300 Subject: KVM: MMU: Replace role.glevels with role.cr4_pae There is no real distinction between glevels=3 and glevels=4; both have exactly the same format and the code is treated exactly the same way. Drop role.glevels and replace is with role.cr4_pae (which is meaningful). This simplifies the code a bit. As a side effect, it allows sharing shadow page tables between pae and longmode guest page tables at the same guest page.
