[PATCH] arm64: vdso32: make vdso32 install conditional
From: Frank van der Linden <hidden>
Date: 2020-08-27 23:40:34
Also in:
lkml
Subsystem:
arm64 port (aarch64 architecture), the rest · Maintainers:
Catalin Marinas, Will Deacon, Linus Torvalds
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 <redacted>
Fixes: 8d75785a8142 ("ARM64: vdso32: Install vdso32 from vdso_install")
