[uml-devel] tls incrementals for 2.6.15 breaking build ... still?

i'm trying to build an 'uptodate' UML guest and see exactly this
'undefined reference to indirect_set_thread_area' (reported in November)
with 2.6.15 and all the incrementals from the patch tarball for
2006-01-08 on user-mode-linux.sf.net.

the comment related to this patch says CONFIG_MODE_ TT 'off' ... but
this email says try it 'on' and that just leads to:
