Subject: Remove noisy warning from default_send_IPI_mask_logical
Date: Fri, 18 Jan 2013 12:58:47 -0500 [thread overview]
Message-ID: <20130118175847.GA27662@redhat.com> (raw)
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:
