Trying minimal configuration scripts/Makefile.kasan:21: CONFIG_KASAN: compiler does not support all opti= ons. Trying minimal configuration x86_64-linux-gcc: warning: unrecognized argument to -fsanitize=3D option: '= kernel-address' lots and lots of this last message ... Caused by the commits that added the kernel address sanitizer. gcc version 4.9.0 cross compiling from Powerpc64. I have added the following patch for today (after which I only got one of the "compiler does not support all options" messages).
