Subject: [PATCH 0/2 v3]intel_pstate: skip this driver if hit Sun X86 servers

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@...com>
and the suggestion,review from Dirk Brandewie <dirk.j.brandewie@...el.com>.
