share/man/man4/man4.x86/amdsmn.4: revision 1.4
sys/arch/x86/pci/amdsmn.c: revision 1.7
sys/arch/x86/pci/amdsmn.c: revision 1.8
sys/arch/x86/pci/amdsmn.c: revision 1.9
sys/arch/x86/pci/amdzentemp.c: revision 1.10
Update to support Family 15h Model 60 temperature sensors.
Changes based on FreeBSD amdtemp driver changes by Conrad Meyer.
XXX: Some code duplication between this driver and amdtemp as
parts of the 15h refresh code share more in common with
older CPUs while accessing the device more like 17h.
--
Note that these drivers are present on some newer AMD Family 15h
processors.
--
Don't mix sign and unsigned operands. Just use size_t for the loop.
--
Apply previous change ("Don't mix sign and unsigned operands. Just use
size_t for the loop.") to another loop variable.
