urgent power management fixes for final 4.18.
These fix the scope of a recent intel_pstate driver optimization
used incorrectly on some systems due to processor identification
ambiguity and fix a few issues in the turbostat utility, including
three recent regressions.
Specifics:
- Use ACPI FADT preferred PM Profile to distinguish Skylake
desktop processors from some server ones with the same model
number in order to limit the scope of the recent IO-wait boost
optimization to servers, as intended (Srinivas Pandruvada).
- Fix several issues in the turbostat utility:
* Fix the -S option on 1-CPU systems (Len Brown).
* Fix computations using incorrect processor core counts (Artem
Bityutskiy).
* Fix the x2apic debug message (Len Brown).
* Fix logical node enumeration to allow for non-sequential
physical nodes (Prarit Bhargava).
* Fix reported family on modern AMD processors (Calvin Walton).
* Clarify the RAPL column information in the man page (Len Brown).
Thanks!
