Too l33t to read release notes? There is no tls subdir since NPTL is the default (and LT is completely gone in FC5). The code in /lib is the TLS code using the correct ABI. The crippled ABI is supported by the code in /lib/i686/nosegneg. This code is *automatically* used if the kernel is compiled to match the glibc version. This happens using the linux-2.6-xen-vdso-note.patch patch in Red Hat's kernel RPMs. --=20 =E2=9E=A7 Ulrich Drepper =E2=9E=A7 Red Hat, Inc. =E2=9E=A7 444 Castro St = =E2=9E=A7 Mountain View, CA =E2=9D=96 --------------enigFFC5E2B3D86A1B4FE242DA05 Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.2 (GNU/Linux) Comment: Using GnuPG with Fedora - http://enigmail.mozdev.org iD8DBQFDaTAd2ijCOnn/RHQRAlAVAJ93qS7hvSdT1t5N2E7LOkfctynJGQCgusaT BZ6t3qKjtHOEESEXdo5mr40= =SK8/ -----END PGP SIGNATURE----- --------------enigFFC5E2B3D86A1B4FE242DA05-- --===============0274949131== Content-Type: text/plain; charset="us-ascii" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit Content-Disposition: inline _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel --===============0274949131==--
