Subject: [PATCH 5/9] selftests/powerpc: Don't run DSCR tests on old systems
Date: Wed, 19 Aug 2020 11:57:23 +1000	[thread overview]
Message-ID: <20200819015727.1977134-5-mpe@ellerman.id.au> (raw)
In-Reply-To: <20200819015727.1977134-1-mpe@ellerman.id.au>

The DSCR tests fail on systems that don't have DSCR, so check for the
DSCR in hwcap and skip if it's not present.
