The patch titled
KVM: MMU: Add missing dirty bit

This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: KVM: MMU: Add missing dirty bit
From: Avi Kivity <[EMAIL PROTECTED]>
If we emulate a write, we fail to set the dirty bit on the guest pte, leading
the guest to believe the page is clean, and thus lose data. Bad.
Fix by setting the guest pte dirty bit under such conditions.
