Subject: [PATCH] [21/48] x86: remove constant_tsc reporting from /proc/cpuinfo' power flags


From: Joerg Roedel <joerg.roedel@....com>

remove the reporting of the constant_tsc flag from the "power management"
field in /proc/cpuinfo.  The NULL value there was replaced by "" because
the former would result in a printout of [8] if the flag is set.
