Dear RT Folks,

I'm pleased to announce the 3.0-rt6 release.

Changes versus 3.0-rt4 (I pushed out a rt5 w/o announce)

  * pin_cpu fix (Yong Zhang)

  * Various compile fixes (Yong Zhang & myself)

  * Serial fix for omap

  * Clocksource lockless watchdog reset

  * Reenabled CONFIG_RCU_BOOST (problem is unreproducible and maybe
    related to NO_HZ, which is still disabled. Paul is working on it!)

  * KGDB work^Whackaround (Jason Wessel)

    The kgdb workaround is really a hack and wants to be replaced by a
    proper overhaul for the console/tty maze.
    See: kgb-serial-hackaround.patch

I just confirmed that this resolves the issue I was seeing while trying
to single step through futex_requeue() on a 2 socket E5680.

Thanks Thomas and Jason,
