Bug#328183: Xen and TLS. Patch avaliable

[Samuel Thibault <samuel.thibault@ens-lyon.org>]

retitle 328183 permit user-level-controlled TLS
thanks

Hi,

We too would like to easily control TLS from user space, so as to be
able to provide TLS in our user-level thread library.

Note that the proposed patch is actually already included upstream,
hence in the debian package too. The only remaining bit is to add the
-mno-tls-direct-seg-refs option to BUILD_CFLAGS, and rebuild. This
will add a very little extra cost to single thread-specific variable
accesses, but it shouldn't be noticeable at all. So please just do it :)

Regards,
Samuel
