This isn't functionally identical. In some cases a hint to disable unit 0 would in fact disable all units.

Introduce the new kernel sub-tree x86 which should contain all the code shared and generalized between our current amd64, i386 and pc98.
This is just an initial step that should lead to a more complete effort. For the moment, a very simple porting of cpufreq modules, BIOS calls and the whole MD specific ISA bus part is added to the sub-tree but ideally a lot of code might be added and more shared support should grow.

Add Pentium D cores into the list that can't handle 12.5% and 25% throttle. My SMP kernel hangs when one of those is selected by powerd. Errata AA21 here:

Attach the cpufreq child devices with specific orders to enforce relative priority of some of the drivers that manage the same state (e.g. ichss0 vs est0). Specifically, powernow, est, and p4tcc are added at order 10, ichss at order 20, and smist at order 30. Previously, some laptops were seeing both ichss0 and est0 attaching and stomping on each other.
XXX: This isn't quite ideal, but works with the existing hacks, I think what we really want instead is a single "speedstep0" device for CPUs that the ichss, est, and smist drivers probe (but with differing priorities).

Increase time we wait for things to settle to 1 millisecond, 10 microseconds is too short.
Always set the cpu to the highest frequency so that we get through boot and don't handicap cpus where powerd(8) is not used.

Make a pass through all drivers checking specs for desired behavior on SMP systems. It appears all drivers except ichss should attach to each CPU and that settings should be performed on each CPU. Add comments about this. Also, add a guard for p4tcc's identify method being called more than once.

Import a rewrite of p4tcc for the cpufreq(4) framework. This includes a bugfix of clearing the On-Demand flag when going back to 100%. It has been tested and works on an IBM R32. Note original work done by Ted Unangst and sobomax@.

Fix the problem with incorrect throttling level reported immediately after reboot. Safter the reboot the TCC is usually in the Automatic mode, in which reading current performance level is likely to produce bogus results make sure to switch it to the On-Demand mode and set to some known performance level. Unfortunately there is no reliable way to check that TCC is in the Automatic mode. Reading bit 4 of ACPI Thermal Monitor Control Register produces 0 regardless of the current mode.

Add new CPU_ENABLE_TCC option, from NOTES:
CPU_ENABLE_TCC enables Thermal Control Circuitry (TCC) found in some Pentium(tm) 4 and (possibly) later CPUs. When enabled and detected, TCC allows to restrict power consumption by using machdep.cpuperf* sysctls. This operates independently of SpeedStep and is useful on systems where other mechanisms such as apm(4) or acpi(4) don't work.
Given the fact that many, even modern, notebooks don't work properly with Intel ACPI, this is indeed very useful option for notebook owners.
