Subject: [PATCH v2 2/4] selftests/arm64: Define top_srcdir for the fp tests
Date: Tue, 19 Apr 2022 21:04:40 +0100	[thread overview]
Message-ID: <20220419200442.1374548-3-broonie@kernel.org> (raw)
In-Reply-To: <20220419200442.1374548-1-broonie@kernel.org>

Some of the rules in lib.mk use a top_srcdir variable to figure out where
the top of the kselftest tree is, provide it.
