+From 8d75785a814241587802655cc33e384230744f0c Mon Sep 17 00:00:00 2001

+Subject: Revert [PATCH] ARM64: vdso32: Install vdso32 from vdso_install
+
+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")
