If you prefer, I can go back to the older version and just disable the warning for the architectures with defconfig build failures. I did a lot of fixes for mips, so at least defconfig and allmodconfig should be fine now, leaving only alpha, nios2, sh and sparc as far as I can tell, at least once Linus merges the asm-generic pull request hat has a bunch of the currently missing fixes.
