From 5d38000b3c97a1079734c0b4c5f87d5b935318cd Mon Sep 17 00:00:00 2001 From: Nathan Lynch Date: Fri, 17 Apr 2015 21:51:38 +0100 Subject: ARM: 8342/1: VDSO: depend on CPU_V7 When targeting ARMv3 (e.g. rpc) and enabling CONFIG_VDSO we get: arch/arm/vdso/datapage.S:13: Error: selected processor does not support ARM mode `bx lr' One fix considered was to use 'ldr pc,lr' for such configurations, but since the VDSO is unlikely to be useful for pre-v7 hardware, just make it depend on CONFIG_CPU_V7.
