Joe,

Between next-20121022 and next-20121023, the serial console (on the ARM
SoC Tegra at least) stopped working. The issue bisects down to this
commit. I haven't had a chance to investigate why yet, I just finished
bisected.

earlyprintk over the same UART works. Once the system has booted, a few
late kernel messages do appear, and then getty/login over the UART
works. So, it's just the printk messages that disappeared.

In case it's relevant, my command-line is:

console=ttyS0,115200n8 loglevel=8 rootwait rw earlyprintk
root=PARTUUID=b2f82cda-2535-4779-b467-094a210fbae7

I'll continue to investigate further tomorrow, but just wanted to give
you a heads-up in case you could immediately see anything obvious in the
code.
