  [ Aurelien Jarno ]
  * debian/patches/any/git-surplus-tls-accounting.diff: backport TLS surplus
    accounting from upstream. (Closes: #964141) (LP: #1914044)

  * Prevent rare deadlock in pthread_cond_signal (LP: #1899800)
  * Cherry-pick upstream patch to fix building with -moutline-atomics
  * Make libc6 provide libc6-lse on arm64.
    Libc6 is now compiled with -moutline-atomics thus the separate binary
    package is dropped. (LP: #1912652)
