x86: mismatched mapcache metadata

ISSUE DESCRIPTION Some shadow paging errors paths will switch the page-tables without updating the currently running vCPU reference. This causes a mismatch between the loaded page-tables and the mapcache metadata which can lead to corruption of the mapcache. IMPACT Privilege escalation, Denial of...
