[PATCH v2 3/7] s390: add CPU field to struct thread_info

[Ard Biesheuvel]

The CPU field will be moved back into thread_info even when
THREAD_INFO_IN_TASK is enabled, so add it back to s390's definition of
struct thread_info.

Note that s390 always has CONFIG_SMP=y so there is no point in guarding
the CPU field with an #ifdef.
