The following trace events are not used and defining them just wastes
memory:
x86_fpu_before_restore
x86_fpu_after_restore
x86_fpu_init_state
Simply remove them.

Can I get an acked-by, and I'll pull this in through my tree (with the
other patches that remove unused events)?
Thanks,

Never mind, I just noticed the tip message that this was already merged and
going upstream.
