Hm, ok... there will be probably some trivial reject...I cannot update those
patches right now since I haven't enough bandwidth.
Just to make sure: you got errors applying until TLS patches, right? Anyhow,
to get the TLS changes only, you need to apply only the following 4 patches:
uml-clean-arch_switch
uml-tls-support-sc-tables
uml-add-tls-support
uml-add-tls-support-debug
They almost apply even on 2.6.12, so should apply for sure on 2.6.13-rc4.
And leave out uml-add-tls-support-flush-empty, it's still broken for now.

Yes, I was probably missing some sleep. Only difference in my patches is that
return value is set to set_tls_entry return value (and this matches with
i386).
Does the system boots ok in that config, including sshd and apps like MySQL /
Apache / Java ? With the previous version of the patches, no TLS data would
work for sure... and sshd still doesn't work on my Sarge (which seems
particularly picky - other people got success with other distros with much
less changes).

Good catch, thanks, even if this isn't going yet to be the *final* fix (since
we aren't likely using the last slot).

Inform me of my mistakes, so I can keep imitating Homer Simpson's "Doh!".
