[added to the 4.1 stable tree] kvm: arm64: Fix EC field in inject_abt64

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Matt Evans <matt.evans@xxxxxxx>

This patch has been added to the 4.1 stable tree. If you have any
objections, please let us know.

===============

[ Upstream commit e4fe9e7dc3828bf6a5714eb3c55aef6260d823a2 ]

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.
