The idea here is to expose the DTS sensors through XENPF_resource_op
and expose it for the user through xenpm.

v3:
 - use msr-index.h instead of adding defines to MSRs in xenpm

v2:
 - moved userland part to xenpm
 - use cpu policy infrastructure instead of inline cpuid

Teddy Astie (3):
  x86/cpu-policy: Infrastructure for CPUID leaf 0x6
  x86/platform: Expose DTS sensors MSR
  xenpm: Add get-intel-temp subcommand

If this is something exposed to users, I think we should update the CHANGELOG.

Thanks.
