[ Upstream commit d05b5e0baf424c8c4b4709ac11f66ab726c8deaf ]
The current initialization of the struct x86_cpu_id via pl4_support_ids[] is partial and wrong. It is initializing "stepping" field with "X86_FEATURE_ANY" instead of "feature" field.
Use X86_MATCH_INTEL_FAM6_MODEL macro instead of initializing each field of the struct x86_cpu_id for pl4_supported list of CPUs. This X86_MATCH_INTEL_FAM6_MODEL macro internally uses another macro X86_MATCH_VENDOR_FAM_MODEL_FEATURE for X86 based CPU matching with appropriate initialized values.
