Subject: [PATCH] kvm: arm64: Fix EC field in inject_abt64

From: [email-masked] (Matt Evans)
Date: Mon, 16 May 2016 13:54:56 +0100

The EC field of the constructed ESR is conditionally modified by ORing in
ESR_ELx_EC_DABT_LOW for a data abort.  However, ESR_ELx_EC_SHIFT is missing
from this condition.
