The kernel has a set of utilities and definitions to deal with x86 cpu features. The x86 KVM selftests don't use them, and instead have evolved to use differing and ad-hoc methods for checking features. The advantage of the kernel feature definitions is that they use a format that embeds the info needed to extract them from cpuid (function, index, and register to use). The first 3 patches massage the related cpuid header files in the kernel side, then copy them into tools/ so they can be included by selftests. The last 2 patches replace the tests checking for cpu features to use the definitions and utilities introduced from the kernel.
