Most of us routinely use a cross-compiler to build the kernel and you're the first one to report the problem. Can you report the compiler invocation that has lead to this error? Have you used a default config or a custom one? > diff --git a/arch/mips/include/asm/auxvec.h b/arch/mips/include/asm/auxvec.h > new file mode 100644 > index 0000000..fbd388c > --- /dev/null > +++ b/arch/mips/include/asm/auxvec.h > @@ -0,0 +1 @@ > +#include <uapi/asm/auxvec.h> You're not supposed to require a header in asm/ merely to include a header of the same name from uapi/asm/ as there are normally -I./arch/mips/include and -I./arch/mips/include/uapi options present both at once, in this order, on the compiler's invocation line. So: #include <asm/auxvec.h> will pull the header from uapi/asm/ if none is present in asm/. Maciej
