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.
