From: Vladimir Murzin Date: Mon, 16 Nov 2015 11:28:17 +0000 (+0000) Subject: arm: KVM: Make kvm_arm.h friendly to assembly code X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=8420dcd37ef34040c8fc5a27bf66887b3b2faf80;p=openwrt%2Fstaging%2Fblogic.git arm: KVM: Make kvm_arm.h friendly to assembly code kvm_arm.h is included from both C code and assembly code; however some definitions in this header supplied with U/UL/ULL suffixes which might confuse assembly once they got evaluated. We have _AC macro for such cases, so just wrap problem places with it.
