Subject: [PATCH v17 02/24] selftests: vm: pkeys: Fix multilib builds for x86
Date: Mon, 20 Jan 2020 14:05:30 +0530	[thread overview]
Message-ID: <185321f63407969349e9cb9a1910bef2beddd031.1579507768.git.sandipan@linux.ibm.com> (raw)
In-Reply-To: <cover.1579507768.git.sandipan@linux.ibm.com>
In-Reply-To: <cover.1579507768.git.sandipan@linux.ibm.com>

This ensures that both 32-bit and 64-bit binaries are generated
when this is built on a x86_64 system. Most of the changes have
been borrowed from tools/testing/selftests/x86/Makefile.
