(Although it took a while for the documentation to catch up with the 
implementation and changes made in the course of patch review, as far as I 
know <http://www.linux-mips.org/wiki/NPTL> is now an accurate description 
of TLS for MIPS.)

Anyone seriously wishing to produce a complete and current and 
copyright-clean description of what the MIPS ABIs now are might wish to 
note that a similar project for (32-bit) Power Architecture has been going 
on since late 2006 and we still haven't quite got to the point of 
releasing a public review draft.  There is a lot of work involved.
