This patch landed in today's linux-next (next-20200221) as commit
5e3c6a312a09. It breaks ARM 32bit build without VDSO enabled in .config:

$ make ARCH=arm multi_v7_defconfig

$ ./scripts/config -e ARM_LPAE -e VIRTUALIZATION -e KVM -d VDSO

$ make ARCH=arm olddefconfig

$ make


drivers/clocksource/arm_arch_timer.c:73:44: error:
‘VDSO_CLOCKMODE_ARCHTIMER’ undeclared here (not in a function)
 static enum vdso_clock_mode vdso_default = VDSO_CLOCKMODE_ARCHTIMER;
