Move x86 architecture dependent per cpu data into a seperate structure and embeded it in per_cpu_region. caller could access architecture dependent member by using prefix 'arch.'. v2->v3: move whose_iwkey, profiling_info and tsc_suspend to x86 v1->v2: rebased on latest repo Tracked-On: #8801 Signed-off-by: hangliu1 <hang1.liu@intel.com> Reviewed-by: Wang, Yu1 <yu1.wang@intel.com> Reviewed-by: Liu, Yifan1 <yifan1.liu@intel.com> Reviewed-by: Chen, Jian Jun<jian.jun.chen@intel.com> Acked-by: Wang, Yu1 <yu1.wang@intel.com>
