From e3f0f36ddf1b2743a0d4ea312996536a9c37e1c7 Mon Sep 17 00:00:00 2001 From: Dave Jones Date: Fri, 18 Jan 2013 12:58:47 -0500 Subject: [PATCH] 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.
