Subject: [PATCH] i386: fix section mismatches for init code with !HOTPLUG_CPU
Date: Tue, 18 Aug 2009 16:41:33 +0100	[thread overview]
Message-ID: <4A8AE7CD020000780001054B@vpn.id2.novell.com> (raw)

Commit 0e83815be719d3391bf5ea24b7fe696c07dbd417 changed the section the
initial_code variable gets allocated in, in an attempt to address a
section conflict warning. This, however created a new section conflict
when building without HOTPLUG_CPU. The apparently only (reasonable) way
to address this is to always use __REFDATA.

Once at it, also fix a second section mismatch when not using
HOTPLUG_CPU.
