Subject: [PATCH 1/6] ACPI: Minimize X2APIC initial messages
Date: Fri, 18 Feb 2011 20:47:06 -0600 [thread overview]
Message-ID: <20110219024705.559950799@gulag1.americas.sgi.com> (raw)
In-Reply-To: <20110219024705.308511527@gulag1.americas.sgi.com>
[-- Attachment #1: minimize-x2apic-msgs --]
[-- Type: text/plain, Size: 1657 bytes --]
Minimize X2APIC messages by printing 8 per line and dropping
the "enabled" flag since that's assumed. It will still print
"disabled" if necessary.
v2: updated to apply to x86-tip
