Subject: [PATCH v2 1/7] arm64: Make basic compat_* types always available
Date: Thu, 5 Jul 2018 14:35:58 -0700 [thread overview]
Message-ID: <20180705213604.18883-2-deepa.kernel@gmail.com> (raw)
In-Reply-To: <20180705213604.18883-1-deepa.kernel@gmail.com>
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.
