[PATCH 4.4 12/86] kvm: arm64: Fix EC field in inject_abt64

[Greg Kroah-Hartman]

4.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Matt Evans <matt.ev...@arm.com>

commit e4fe9e7dc3828bf6a5714eb3c55aef6260d823a2 upstream.

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.
