2017-01-04 Thread Andrew Cooper
struct cpuid_policy will eventually be a complete replacement for the cpuids[] array, with a fixed layout and named fields to allow O(1) access to specific information. For now, the CPUID content is capped at the 0xd and 0x801c leaves, which matches the maximum policy that the toolstack will g
