Re: [libvirt] [PATCH v2 14/30] cpu_x86: Allow multiple signatures for a CPU model

CPU signatures in the cpu_map serve as a hint for CPUID to CPU model matching algorithm. If the CPU signatures matches any CPU model in the cpu_map, this model will be the preferred one. This works out well and solved several mismatches, but in real world CPUs which should match a single CPU model may be produced with several different signatures. For example, low voltage Broadwell CPUs for laptops and Broadwell CPUs for servers differ in CPU model numbers while we should detect them all as Broadwell CPU model. This patch adds support for storing several signatures for a single CPU model to make this hint useful for more CPUs. Later commits will provide additional signatures for existing CPU models, which will correct some results in our CPU test suite.
