Subject: [PATCH 01/29] KVM: MMU: Check for root_level instead of long mode
Date: Fri, 10 Sep 2010 17:30:38 +0200 [thread overview]
Message-ID: <1284132667-18620-2-git-send-email-joerg.roedel@amd.com> (raw)
In-Reply-To: <1284132667-18620-1-git-send-email-joerg.roedel@amd.com>
The walk_addr function checks for !is_long_mode in its 64
bit version. But what is meant here is a check for pae
paging. Change the condition to really check for pae paging
so that it also works with nested nested paging.
