Subject: [PATCH 0/2] x86: TLS regression fixes

The recent TLS hardening work broke at least one game.  This series
fixes it.  I'm not entirely happy with this series, but I'm far from
entirely happy with the TLS or LDT code in the first place.

Thoughts?

Andy Lutomirski (2):
  x86, tls, ldt: Stop checking lm in LDT_empty
  x86, tls: Interpret an all-zero struct user_desc as "no segment"
