Subject: [PATCH] kvm: external module: support building against Windriver 2.0 (kernel 2.6.21)
Date: Thu, 12 Mar 2009 17:37:18 +0000 (UTC)	[thread overview]
Message-ID: <loom.20090312T173612-632@post.gmane.org> (raw)

This is needed to compile kvm in a Windriver 2.0 distribution
(kernel 2.6.21). This kernel has an include file marker.h, but
trace_mark is not defined there. So the compat code in
kernel/include-compat/linux/marker.h is not included.
