x86/apic: Remove noisy zero-mask warning from default_send_IPI_mask_logical()
Since circa 3.5, we've had dozens of reports of people hitting this warning. Forwarded reports have been met with silence, so just remove the warning if no-one cares. Example reports: https://bugzilla.redhat.com/show_bug.cgi?id=797687 https://bugzilla.redhat.com/show_bug.cgi?id=867174 https://bugzilla.redhat.com/show_bug.cgi?id=894865 Signed-off-by: Dave Jones <davej@redhat.com> Cc: Andrew Morton <akpm@linux-foundation.org> Link: http://lkml.kernel.org/r/20130118175847.GA27662@redhat.com Signed-off-by: Ingo Molnar <mingo@kernel.org>
