Subject: [PATCH 5/5] selftests: vdso: Support arm64 in getcpu() test
Date: Fri, 5 Jun 2020 14:11:31 +0100 [thread overview]
Message-ID: <20200605131131.16491-6-broonie@kernel.org> (raw)
In-Reply-To: <20200605131131.16491-1-broonie@kernel.org>
arm64 exports the vDSO ABI with a version of LINUX_2.6.39 and symbols
prefixed with __kernel rather than __vdso. Update the getcpu() test to
handle this.
