The build of tilegx allmodconfig was failing with errors like:
../arch/tile/include/asm/div64.h:5:15: error: unknown type name 'u64'
  static inline u64 mul_u32_u32(u32 a, u32 b)

../arch/tile/include/asm/div64.h:9:21: error: implicit declaration of
    function 'mul_u32_u32' [-Werror=implicit-function-declaration]

The simplest solution was to include the types header file.

linux-next is still failing for this error. Who will pick this up?

Presumably the tip tree (timers/core).  Added Thomas to cc.
