Reduce special casing of xen_cpuid() by using cpu capabilities instead of faked cpuid nodes. This cleanup enables us remove the hypervisor specific set_cpu_features callback as the same effect can be reached via setup_[clear|force]_cpu_cap(). Removing the rest faked nodes from xen_cpuid() requires some more work as the remaining cases (mwait leafs and extended topology info) have to be handled at the consumer sides of this information. Changes in V3: - rewrite patch 9 (xsave) to use xgetbv instruction to test for osxsave availability (Andrew Cooper) Changes in V2: - added several features to this scheme - removed hypervisor specific set_cpu_features() callbacks Cc: Alok Kataria <akataria@xxxxxxxxxx> Cc: Thomas Gleixner <tglx@xxxxxxxxxxxxx> Cc: Ingo Molnar <mingo@xxxxxxxxxx> Cc: "H.
