Subject: [PATCH 2.6.14] ppc32: Fix CONFIG_PRINTK=n building
Date: Tue, 8 Nov 2005 15:36:31 -0700 [thread overview]
Message-ID: <20051108223631.GR3839@smtp.west.cox.net> (raw)
The following patch is needed to allow PRINTK=n to work on ppc32.
Direct calls to printk from asm files can't be magically removed so we
have to do it manually.
