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. [masahiro: Import Jeroen's work for U-Boot: http://patchwork.ozlabs.org/patch/375026/ Tweak sed script a little to avoid garbage '#' for GCC case, like #define NR_PAGEFLAGS 23 /* __NR_PAGEFLAGS # */ ] Signed-off-by: Jeroen Hofstee <jeroen@myspectrum.nl> Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Reviewed-by: Matthias Kaehlcke <mka@chromium.org> Tested-by: Matthias Kaehlcke <mka@chromium.org>
