- get rid of "magick" values in code and make sysctl's reflecting reality
on processor versions which have one or another frequency "forbidden"
due to errata.

rev.1.1040. It is a miscellaneous isa+pci driver, but came back
described as a pci-only driver and placed in an i4b pci subsection
after its migration to /sys/conf/NOTES. Put it back where it used to
be, fully unsorted in the `Miscellaneous hardware' section. Reduced
nearby disorder in this section by moving configuration of the digi
driver to where it was for the old digiboard drivers, so that the
order at least matches the order in the table of contents.
- references to removed math emulators for NPX_DEBUG
- header for the null set of mandatory devices
- reference to the removed (and bogus when it existed) sysctl
kern.timecounter.method.
FIxed some nearby disorder (descriptions of CPU_BLUELIGHTNING_3X,
CPU_DIRECT_MAPPED_CACHE, CPU_DISABLE_CMPXCHG, CPU_DISABLE_SSE,
CPU_ELAN_XTAL and CPU_SOEKRIS, and options for all of these except
CPU_DIRECT_MAPPED_CACHE).
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.

lots of old interfaces, and digi now supports all cards that dgb
supported. The author of the driver says that this is no longer
necessary.

or whose drivers haven't even compiled for years.
The loran hardware was very unique, and only a few copies of it ever
existed. It used the old COMPAT_ISA_DRIVER and when the author was
contacted, he indicated that he had no intention of ever updating this
driver and it was no longer relevant to the FreeBSD world and can be
removed without impact to anybody.

should only be used if they are enabled in the BIOS. Now that we support
enumerating CPUs using the ACPI MADT, any HTT machine using ACPI should
respect the BIOS setting. For HTT machines with ACPI disabled in the
kernel, the MPTABLE_FORCE_HTT kernel option can be used to try to probe HTT
CPUs like have done in the past for the MP Table case. This option should
only be enabled if HTT is enabled in the BIOS.
- Compile 'device acpi' into GENERIC by default as well. Note that
the beastie loader menu item to disable ACPI still works if ACPI is
compiled into the kernel.

enable strict checks of the AML. Our default behavior will be to relax
checks to work on as many platforms as possible. Also clean up and document
other ACPI options while I'm here.
