I'm setting the compilation off now. I will give it a whirl some time 
Saturday or Sunday.

Before I did that I created kernel/sched.s and have verified that the 
two error locations are accesses to it_func_ptr as you suspected.


ldx     [%g1+%lo(__tracepoint_sched_wakeup)+28], %l0    !, it_func_ptr
and
ldx     [%g3], %l2      !, it_func_ptr

with v3 of you patches applied it uses +32 to get the offset of 
it_func_ptr so that looks good.

Will do.
