- Add support for Family 12h, 14h and 15h processors.

- 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).

Restore (undocumented) support for early revisions and add more comments.

Improve amdtemp(4) significantly:

- 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.
