CPU Temp Warnings

[Justin Hibbits]

Hi Matt,

Yes, it would require an svn up to head and buildworld+buildkernel.
Alternatively, there are snapshots available on the FTP server that
include the change.

Yet another alternative, for now, if you're feeling adventurous enough
to cherry-pick the patch, the relevant patch is r277314, or a simple
drop-in of the sys/dev/iicbus/adt746x.c from head would work (still
have to compile from source, but everything is 10 except this file).
I'm in the process of creating a patch to be included in 10.2, which
you could upgrade to at release time as well.
