The CPUID functions were stored in multiple arrays according to a specified prefix of those. This made it very hard to add another prefix to store KVM CPUID features (0x40000000). Instead of hardcoding a third array this patch changes the approach used: The code is refactored to use a single array where the CPUID functions are stored ordered by the cpuid function so that they don't depend on the specific prefix and don't waste memory. The code is also less complex using this approach. A trateoff to this is the change from O(N) complexity to O(N^2) in x86DataAdd and x86DataSubtract. The rest of the functions were already using O(N^2) algorithms.
LibVirt : simple API for virtualization Libvirt is a C toolkit to interact with the virtualization capabilities of recent versions of Linux (and other OSes). It is free software available under the GNU Lesser General Public License. Virtualization of the Linux Operating System means the ability to run multiple instances of Operating Systems concurrently on a single hardware system where the basic resources are driven by a Linux instance. The library aim at providing long term stable C API initially for the Xen paravirtualization but should be able to integrate other virtualization mechanisms if needed.

Description
Libvirt provides a portable, long term stable C API for managing the
virtualization technologies provided by many operating systems. It
includes support for QEMU, KVM, Xen, LXC, bhyve, Virtuozzo, VMware
vCenter and ESX, VMware Desktop, Hyper-V, VirtualBox and the POWER
Hypervisor.
