From cf0c3e68aa81f992b0301f62e341b710d385bf68 Mon Sep 17 00:00:00 2001 From: Jeroen Hofstee Date: Fri, 21 Apr 2017 15:21:11 +0900 Subject: kbuild: fix asm-offset generation to work with clang KBuild abuses the asm statement to write to a file and clang chokes about these invalid asm statements. Hack it even more by fooling this is actual valid asm code.
