This set of patches is to add support for Zhaoxin Family 7 CPUs. With these patches, the kernel can identify Zhaoxin CPUs features and Zhaoxin CPU topology information.
LeoLiu-oc (6): x86/cpu: Create Zhaoxin processors architecture support file x86/cpu: Remove redundant cpu_detect_cache_sizes() call x86/cpu/centaur: Replace two-condition switch-case with an if statement x86/cpu/centaur: Add Centaur family >=7 CPUs initialization support x86/cpufeatures: Add Zhaoxin feature bits x86/cpu: Add detect extended topology for Zhaoxin CPUs
