Subject: x86/intel: Move mcu_opt_ctrl_* into __ro_after_init
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=88b4ea080cd2ee502b08754ed7adbd7ee5e30a89;p=people%2Fandrewcoop%2Fxen.git

x86/intel: Move mcu_opt_ctrl_* into __ro_after_init

They're only modified by set_in_mcu_opt_ctrl() which is an __init function.

No functional change.
