Subject: [PATCH v3 1/5] arm64: vdso: Provide a define when building the vDSO
Date: Wed, 19 Aug 2020 13:13:14 +0100	[thread overview]
Message-ID: <20200819121318.52158-2-broonie@kernel.org> (raw)
In-Reply-To: <20200819121318.52158-1-broonie@kernel.org>

Provide a define identifying if code is being built for the vDSO to help
with writing headers that are shared between the kernel and the vDSO.
