Subject: [PATCH] arm64: vdso32: make vdso32 install conditional
Date: Thu, 27 Aug 2020 23:40:12 +0000 [thread overview]
Message-ID: <20200827234012.19757-1-fllinden@amazon.com> (raw)
vdso32 should only be installed if CONFIG_COMPAT_VDSO is enabled,
since it's not even supposed to be compiled otherwise, and arm64
builds without a 32bit crosscompiler will fail.
Signed-off-by: Frank van der Linden <fllinden@amazon.com>
