[PATCH 5.4 096/107] ARM64: vdso32: Install vdso32 from vdso_install

From: Greg Kroah-Hartman
Date: Mon Aug 24 2020 - 05:36:02 EST


From: Stephen Boyd <swboyd@xxxxxxxxxxxx>

[ Upstream commit 8d75785a814241587802655cc33e384230744f0c ]

Add the 32-bit vdso Makefile to the vdso_install rule so that 'make
vdso_install' installs the 32-bit compat vdso when it is compiled.

Fixes: a7f71a2c8903 ("arm64: compat: Add vDSO")
