From bf9c95e23324cbaf2e58fc3f0cbdc73137f2d1ca Mon Sep 17 00:00:00 2001 From: Michael Ellerman Date: Wed, 20 Nov 2019 13:37:23 +1100 Subject: [PATCH] selftests/powerpc: spectre_v2 test must be built 64-bit 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.
