Subject: [PATCH 3/6 v2] kvm: powerpc: allow guest control "G" attribute in mas2
Date: Thu, 1 Aug 2013 16:42:35 +0530 [thread overview]
Message-ID: <1375355558-19187-4-git-send-email-Bharat.Bhushan@freescale.com> (raw)
In-Reply-To: <1375355558-19187-1-git-send-email-Bharat.Bhushan@freescale.com>
"G" bit in MAS2 indicates whether the page is Guarded.
There is no reason to stop guest setting "E", so allow him.
