Subject: [PATCH] selftests/powerpc: spectre_v2 test must be built 64-bit
Date: Wed, 20 Nov 2019 13:39:24 +1100 [thread overview]
Message-ID: <20191120023924.13130-1-mpe@ellerman.id.au> (raw)
The spectre_v2 test must be built 64-bit, it includes hand-written asm
that is 64-bit only, and segfaults if built 32-bit.
Fixes: c790c3d2b0ec ("selftests/powerpc: Add a test of spectre_v2 mitigations")
Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
