Subject: [PATCH 2/2] setarch: add arm and aarch64 architectures to transition rules
Date: Tue, 23 Jun 2020 16:56:20 +0200
Message-ID: <20200623145620.2669920-3-gladkov.alexey@gmail.com> (raw)
In-Reply-To: <20200623145620.2669920-1-gladkov.alexey@gmail.com>

Since aarch64 kernel can be configured with compat 32-bit support
enabled, extend translation rules in a way similar to x86/x86_64.
