Subject: [PATCH] kvm: arm64: Fix EC field in inject_abt64
Date: Mon, 16 May 2016 13:54:56 +0100 [thread overview]
Message-ID: <5739C320.6010602@arm.com> (raw)
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.
