From f80f6531b47c538b69769ada5e9fbacad085b34d Mon Sep 17 00:00:00 2001 From: Nathan Lynch Date: Sat, 18 Apr 2015 00:39:16 +0100 Subject: [PATCH] ARM: 8344/1: VDSO: honor CONFIG_VDSO in Makefile When CONFIG_VDSO=n, the build normally does not enter arch/arm/vdso/ because arch/arm/Makefile does not add it to core-y. However, if the user runs 'make arch/arm/vdso/' the VDSO targets will get visited. This is because the VDSO Makefile itself does not consider the value of CONFIG_VDSO. It is arguably better and more consistent behavior to generate an empty built-in.o when CONFIG_VDSO=n and the user attempts to build arch/arm/vdso/. It's nicer because it doesn't try to build things that Kconfig dependencies are there to prevent (e.g. the dependency on AEABI), and it's less confusing than building objects that won't be used in the final image.
