[Midnightbsd-cvs] src: kern_cpu.c: Add partial support for Intel Turbo Boost technology on

[laffer1 at midnightbsd.org]

Log Message:
-----------
Add partial support for Intel Turbo Boost technology on newer i5/i7 and Xeons.

ACPI may report extra level with frequency 1MHz above the nominal to
control Intel Turbo Boost operation. It is not a bug, but feature:
dev.cpu.0.freq_levels: 2934/106000 2933/95000 2800/82000 ...
In this case value 2933 means 2.93GHz, but 2934 means 3.2-3.6GHz.

based on patch by mav @ freebsd
