Li Fei1 01b54241c6 hv: ept: only treak execution right for large pages ... To mitigate the page size change MCE vulnerability (CVE-2018-12207), ACRN would clear the execution permission in the EPT paging-structure entries for large pages and then intercept an EPT execution-permission violation caused by an attempt to execution an instruction in the guest. However, the current code would clear the execution permission in the EPT paging- structure entries for small pages too when we clearing the the execution permission for large pages. This would trigger extra EPT violation VM exits. This patch fix this issue.
