Intel inclusion
category: feature
feature: IPI Virtualization
bugzilla: https://gitee.com/openeuler/intel-kernel/issues/I5ODSC


CVE: N/A

-------------------------------------------------

The introduction of VMX tertiary features like IPI virtualization
causes the change of the size of struct cpu_info_x86. This patch
tries to put the tertiary features on a separate data structure.
