- Remove all attempts to guess physical temperature using DiodeOffset.
There are too many reports that it varies wildly depending on motherboard.
Instead, if it is known to scale well and its offset is known from other
temperature sensors on board, the user may set "dev.amdtemp.0.sensor_offset"
tunable to compensate the difference. Document the caveats in amdtemp(4).
- Add a quirk for Socket AM2 Revision G processors. These processors are
known to have a different offset according to Linux k8temp driver.
- Warn about Family 10h Erratum 319. These processors have broken sensors.
- Report temperature in more logical orders under dev.amdtemp node. For
example, "dev.amdtemp.0.sensor0.core0" is now "dev.amdtemp.0.core0.sensor0".
- Replace K8, K10 and K11 with official processor names in amdtemp(4).

- Improve newer AMD processor support (Family 0Fh Revision F and later).
- Adjust offset if DiodeOffet is set and valid. Note it is experimental
but it seems to give us more realistic temperatures. Newer Linux driver
blindly adds 21C for Family 0Fh desktop processors, however.
- Always populate dev.cpu and dev.amdtemp sysctl trees regardless of probe
order for consistency. Previously, dev.cpu.N.temperature was not populated
if amdtemp was loaded later than ACPI CPU driver and temperatures were not
accessible from dev.amdtemp.N.sensor0 tree for Family 10h/11h processors.
- Read the CPUID from PCI register instead of CPUID instruction to prevent
possible revision mismatches on multi-socket system.
- Change macros and variables to make them closer to AMD documents.
- Fix style(9) nits and improve comments.

The newbus lock is responsible for protecting newbus internIal structures,
device states and devclass flags. It is necessary to hold it when all
such datas are accessed. For the other operations, softc locking should
ensure enough protection to avoid races.
Newbus lock is automatically held when virtual operations on the device
and bus are invoked when loading the driver or when the suspend/resume
take place. For other 'spourious' operations trying to access/modify
the newbus topology, newbus lock needs to be automatically acquired and
dropped.
For the moment Giant is also acquired in some key point (modules subsystem)
in order to avoid problems before the 8.0 release as module handlers could
make assumptions about it. This Giant locking should go just after
the release happens.
Please keep in mind that the public interface can be expanded in order
to provide more support, if there are really necessities at some point
and also some bugs could arise as long as the patch needs a bit of
further testing.
Bump __FreeBSD_version in order to reflect the newbus lock introduction.
