Subject: [PATCH 3.14 26/30] arm64: KVM: Fix TLB invalidation by IPA/VMID
Date: Wed, 8 Jul 2015 00:34:25 -0700 [thread overview]
Message-ID: <20150708073207.913859016@linuxfoundation.org> (raw)
In-Reply-To: <20150708073155.841723465@linuxfoundation.org>
3.14-stable review patch. If anyone has any objections, please let me know.
------------------
From: Marc Zyngier <marc.zyngier@arm.com>
commit 55e858b75808347378e5117c3c2339f46cc03575 upstream.
It took about two years for someone to notice that the IPA passed
to TLBI IPAS2E1IS must be shifted by 12 bits. Clearly our reviewing
is not as good as it should be...
Paper bag time for me.
