Re: [Xen-devel] pv_ops dom0 BUG in xen_flush_tlb_others

The BUG() is triggered because the CPU mask is empty.  So maybe it's not
a xen bug at all, just a weird occurence in the kernel -
native_flush_tlb_others doesn't have such a check.

Interesting. I've never seen it trigger, but I think we can easily remove the test with no bad effects.
