It would be great to have an Ack from sparc folks.
I had to recalculate the values of their TI_* constants
and I don't have a sparc box to test it.

Using asm-offsets.c for that seems to be impossible on sparc
as sparc's asm-offsets.c depends on sched.h which depends again
on thread_info.h...
Resolving this circular dependency without the ability to run-time
test my changes was too risky for me.

Thanks,
