I'm committing these trivial non-semantic patches, I'm actually
running the kernel without any ti->task pointer now (the previous
patch I sent out).
So I'll do the mutex debug patch and the stack dump patch as just he
obvious cleanup patches.
Those are the "purely legacy reasons for a bad calling convention",
and I'm ok with those during the rc series to make it easier for
people to play around with this.
With he goal being that I'm hoping that we can then actually get rid
of this (at least on x86-64, even if we leave it in some other
architectures) in 4.8.
