Subject: tipc: add __read_mostly annotations to several global variables
X-Git-Tag: omap-for-v3.7-rc1/fixes-cpufreq-signed~47^2~306
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=61cdd4d80b29cfdee45920238eea2d1fbb51f922;p=pandora-kernel.git

tipc: add __read_mostly annotations to several global variables

Added to the following:

 - tipc_random
 - tipc_own_addr
 - tipc_max_ports
 - tipc_net_id
 - tipc_remote_management
 - handler_enabled

The above global variables are read often, but written rarely. Use
__read_mostly to prevent them being on the same cacheline as another
variable which is written to often, which would cause cacheline
bouncing.
