Zeng Guang 3587531638 KVM: x86: Allow userspace to set maximum VCPU id for VM ... Introduce new max_vcpu_ids in KVM for x86 architecture. Userspace can assign maximum possible vcpu id for current VM session using KVM_CAP_MAX_VCPU_ID of KVM_ENABLE_CAP ioctl(). This is done for x86 only because the sole use case is to guide memory allocation for PID-pointer table, a structure needed to enable VMX IPI. By default, max_vcpu_ids set as KVM_MAX_VCPU_IDS.
