Paolo Bonzini caadf876bb KVM: introduce CONFIG_KVM_COMMON ... CONFIG_HAVE_KVM is currently used by some architectures to either enabled the KVM config proper, or to enable host-side code that is not part of the KVM module. However, CONFIG_KVM's "select" statement in virt/kvm/Kconfig corresponds to a third meaning, namely to enable common Kconfigs required by all architectures that support KVM. These three meanings can be replaced respectively by an architecture-specific Kconfig, by IS_ENABLED(CONFIG_KVM), or by a new Kconfig symbol that is in turn selected by the architecture-specific "config KVM". Start by introducing such a new Kconfig symbol, CONFIG_KVM_COMMON. Unlike CONFIG_HAVE_KVM, it is selected by CONFIG_KVM, not by architecture code, and it brings in all dependencies of common KVM code. In particular, INTERVAL_TREE was missing in loongarch and riscv, so that is another thing that is fixed.
