That said, this is *not* in the current linux kernel. And I question
the wisdom of changing the user-space ABI for TLS for a single CPU.
I think you'd better leave this out until it's actually accepted upstream.
with out above fix Octeon user mode binary can not be correctly run on QEMU.
This was the behavior on actual hardware which we noticed when we were debugging the
user mode binary on Octeon board.
(there are instructions in user mode ELF of Octeon which read k0 and k1 values)
