Gaah. You'll need something like this too

-       DEFINE(TASK_CPU, offsetof(struct task_struct, cpu));
+       DEFINE(TASK_CPU, offsetof(struct task_struct, thread_info.cpu));

in arch/parisc/kernel/asm-offsets.c.

And really, it should probably be renamed as TASK_TI_CPU, but then you
have to rename all the uses too.

There might be other details like that lurking.
