Subject: [PATCH] x86/kernel: use pr_<level>() and dev_<level>

arch/x86/kernel/* use a mixture of printk(KERN_<level> ) and pr_<level>().
This patch converts the bulk of printk(KERN_<level> ) to pr_<level>() and
uses dev_dbg() instead of the dev_printk(KERN_DEBUG,). All pr_warning()
calls have been replaced with pr_warn().

Not sure what to do about the printk(KERN_DEFAULT) and printk() without a
log level.
