#275 oprofile-1.0.0 fails to recognize AMD Athlon-XP CPU

[Andrew]

Hello,

oprofile-1.0.0 doesn't recognize AMD Athlon CPU family.

Problem is in op_cpu_type.c code ignoring 0x6 CPU family which corresponds to AMD Athlon/Athlon-XP CPUs. Attached patch fixes this issue and I'm able to use oprofile on this host again.

$ ./operf
Unable to obtain cpu_type
Verify that a pre-1.0 version of OProfile is not in use.
If the /dev/oprofile/cpu_type file exists, locate the pre-1.0 OProfile
installation, and use its 'opcontrol' command, passing the --deinit option.
Unable to ascertain cpu type. Exiting.
