Increase KVM_MAX_VCPUS to 2048 so we can run larger virtual machines. Notable changes: * KVM_CAP_MAX_VCPUS will return 2048. * KVM_MAX_VCPU_IDS will increase from 4096 to 8192. * KVM_HV_MAX_SPARSE_VCPU_SET_BITS will increase from 16 to 32. * CPUID[HYPERV_CPUID_IMPLEMENT_LIMITS (00x40000005)].EAX will now be 2048. * struct kvm will increase from 40336 B to 40464 B. * struct kvm_arch will increase from 34488 B to 34616 B. * struct kvm_ioapic will increase from 5240 B to 9848 B. * vcpu_mask in kvm_hv_flush_tlb will increase from 128 B to 256 B. * vcpu_mask in kvm_hv_send_ipi will increase from 128 B to 256 B. * vcpu_bitmap in ioapic_write_indirect will increase from 128 B to 256 B. * vp_bitmap in sparse_set_to_vcpu_mask will increase from 128 B to 256 B. * sparse_banks in kvm_hv_flush_tlb will increase from 128 B to 256 B. * sparse_banks in kvm_hv_send_ipi will increase from 128 B to 256 B.
