[XenPPC] Error msgs when running gpfs on dom0

[Dilma DaSilva <dilma@xxxxxxxxxxxxxx>]

I'm successfully running the file system gpfs on dom0. The mount
operation issues some kernel messages (included below), but it
succeeds and the file system is working.
These messages do not appear when running without Xen (on the same
linux kernel).

Is this "badness in __mutex_unlock_slowpath" familiar to anyone?

Thanks,

Dilma
