Oracle Sun servers(X86) have power capping features that work via ACPI _PPC method, patch No.1 is used to skip this driver if Oracle Sun server and _PPC detected. Patch No.2 introduces a kernel command line parameter for those who would like to enable intel_pstate on Sun X86 servers and be aware of the risk.
Compiled and tested with stable-3.18-rc5 on Oracle Sun server X4-2 series.
Thanks test and review by Linda Knippers <linda.knippers@hp.com> and the suggestion,review from Dirk Brandewie <dirk.j.brandewie@intel.com>. -- v2: fix break HP Proliant issue. v3: expand the hardware vendor list.
