The living envy the dead. This may be the best macro soup in the whole kernel. The code is so horrible because it's a functions that is used very frequently in the kernel. Breathe at it, you get an extra instruction and that expanded a few thousand times acrosst he kernel. And quite often I had to pick the ugly solution because the bogus warnings as you are experiencing are haunting the implementation forever. Since a few days I'm using binutils 2.20 and gcc 4.5.0; all defconfigs are building ok. I'm uploading the rpms (see list below signature) I built for my own use to ftp://ftp.linux-mips.org/pub/linux/mips/crossdev/ http://ftp.linux-mips.org/pub/linux/mips/crossdev/ These were built on F12 and come with no userland libraries so are perfect for your kernel-only use.
