Subject: [PATCH 1/6] arm64: Make basic compat_* types always available
Date:   Mon,  2 Jul 2018 22:44:17 -0700
Message-Id: <20180703054422.12089-2-deepa.kernel@gmail.com>
In-Reply-To: <20180703054422.12089-1-deepa.kernel@gmail.com>
References: <20180703054422.12089-1-deepa.kernel@gmail.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

As we repurpose more compat syscalls to be used in non CONFIG_COMPAT
usecases as part of solving y2038, we need to make these basic types
available unconditionally.
