It might be useful for this printk() to indicate whether it was the
standard or the guest log level which was adjusted.
It does, by printing the string thresh_adj currently points to.

Ah - so it does.  Sorry for the noise.

I am guessing from the looks of these that I should augment my
keyhandler cleanup to also be able to register irq handlers from outside
of common/keyhandler.c
Yeah, I was actually surprised you got away without (i.e. that all of
them lived in this one file so far).

It surprised me as well, but I didn't fancy adding it simply for the sake of adding it.
