cf2e6c54c9
This patch add ability to test /proc/cpuinfo data we're interested in at the moment. The code provides the following functionality - cpu_init, to parse cpuinfo and check if the host cpu we're running on is suitable enough for FPU checkpoint/restore. If FPU present then there must be at least fxsave capability present - cpu_set_feature/cpu_has_feature helpers which provides to test certain bits and set them where needed (we need to set bits when parse cpuinfo) Note, we reserve space for all cpuinfo bits known by the kernel at moment, while use only three FPU related bits for a while. This is done because we might need to use or find out other features in future. After all it's just 40 bytes of memory needed to keep all possible bits.
