Cover letter [PATCH 0/2] i386: arch_capabilities fixes + migratability
This series works around KVM bugs that affect the arch_capabilities feature. One bug made the feature be enabled incorrect on AMD hosts, and another one made the feature unsafe to enable on most Intel hosts. With the work around, we can finally make arch_capabilities a migratable feature.
Unfortunately, the work around has the side effect of making arch_capabilities unavailable on hosts without hardware support for the feature until one of the KVM bugs is fixed.
