Hi all,
(Since patches 1 and 2 involve changes to x86 vendors other than Intel,
I have also cc'd friends from AMD and Zhaoxin.)
These are the ones I was going to clean up a long time ago:
* Fixup CPUID 0x80000005 & 0x80000006 for Intel (and Zhaoxin now).
* Add cache model for Intel CPUs.
* Enable 0x1f CPUID leaf for specific Intel CPUs, which already have
this leaf on host by default.
If you run into vendor specific branches while refactoring the topology-related
code, please feel free to treat Intel and Zhaoxin as one class. For every
topology CPUID leaf(0x0B, 0x1F, ...) so far, Zhaoxin has followed the Intel SDM
definition exactly.
