Author: loos Date: Sat Feb 14 18:37:36 2015 New Revision: 278768 URL: https://svnweb.freebsd.org/changeset/base/278768 Log: MFC r276296, r277207: Make consistent use of the correct debug macros across the file. Fix the C -> K temperature conversion for the dev.cpu.0.temperature sysctl. Remove the unused temperature conversion macros.
