[$] printk() and KERN_CONT

A nearly year-old "fix" to the main logging function used in the kernel,printk(), changed the appearance of some log messages in anunexpected way, at least for some.Messages that had appeared on a single line will now be spread over multiplelines as each call to printk() begins a new line in the outputunless the KERN_CONT flag is used.That is how a comment in the kernel code says it should work, but thechange was made by Linus Torvalds without any discussion orfanfare, so it took some by surprise.
