Subject: Regression due to 7ff9554 "printk: convert byte-buffer to variable-length

For me, next-20120508 prints nothing when booted, and I think also
hangs. To solve this, I reverted:

7ff9554 printk: convert byte-buffer to variable-length record buffer

In order to build, I also had to revert:

c4e00da driver-core: extend dev_printk() to pass structured data

Note: I'm running on an ARM system using a serial console, with
earlyprintk enabled.
