Subject: [PATCH 6/6] ARM: kvm: TMP: Commit the hyp page tables to main memory
Date: Thu, 14 Nov 2013 14:37:46 -0500	[thread overview]
Message-ID: <1384457866-16135-7-git-send-email-santosh.shilimkar@ti.com> (raw)
In-Reply-To: <1384457866-16135-1-git-send-email-santosh.shilimkar@ti.com>

This is a temporary hack which I have to use to avoid a weired crash while
starting the guest OS on Keystsone. They are random crashesh while the
guest os userspace starts. Additional data point is, it seen only with first
guest OS lanch. Subsequest guest OS starts normal.
    
I still don't know why this is needed but it helps to get around the issue
and hence including the patch in the series for the discussion
