So I spent a while thinking hard about how I could make Tobin do another
round or two on these patches.  But then I figure that it's the holidays,
and I should just apply them.  So that's done.  Thanks for all of your
work on this!

That said...

 - I don't quite understand why you capitalize "kernel" everywhere.  I
   vaguely recall some sort of discussion on that.  To me it looks
   strange...oh well.

 - There's a dangling reference to printk-formats.txt in lib/vsprintf.c
   that we'll want to fix up.

 - The vsprintf kerneldoc currently gets pulled into the big "kernel API"
   dumpster.  Someday, it would be nice to turn printk-formats.rst into a
   "how to output data from the kernel" section, with documentation on
   vnsprintf, printk, trace_printk, and format strings all in one place.
   What a fine day that would be...

Thanks again,
