Subject: [PATCH 3/6 v5] kvm: powerpc: allow guest control "G" attribute in mas2
Date: Thu, 19 Sep 2013 11:32:43 +0530	[thread overview]
Message-ID: <1379570566-3715-4-git-send-email-Bharat.Bhushan@freescale.com> (raw)
In-Reply-To: <1379570566-3715-1-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  "G", so allow him.
