Subject: [PATCH] [POWERPC] Initialize lockdep earlier
Date: Wed, 07 May 2008 10:25:34 +1000 [thread overview]
Message-ID: <20080507002714.B2FEFDDECA@ozlabs.org> (raw)
This moves lockdep_init() to before udbg_early_init() as the later
can call things that acquire spinlocks etc... This also makes printk
safer to use earlier.
