Not tested at all, but this should not change anything.

OK?

Thanks,
Roland


	* sysdeps/tile/nptl/tls.h (TLS_DEFINE_INIT_TP): New macro.
	* sysdeps/unix/sysv/linux/tile/nptl/createthread.c: File removed.

Built and tested, seems to work fine, looks correct.

Committed.

Your nptl/ removal all looks good, but I would encourage you to also remove
the vfork/pt-vfork distinction as we've done for most other machines now.


Thanks,
Roland
