+Subject: [PATCH] smbios: Add missing member of type 4 for smbios 3.0
+
+According to smbios 3.0 spec, for processor information (type 4),
+it adds three new members (Core Count 2, Core enabled 2, thread count 2) for 3.0, Without this three members, we can not get correct cpu frequency from dmi,
+Because it will failed to check the length of Processor Infomation in DMI.
+
+The corresponding codes in kernel is like:
+    if (dm->type == DMI_ENTRY_PROCESSOR &&
+        dm->length >= DMI_ENTRY_PROCESSOR_MIN_LENGTH) {
+        u16 val = (u16)get_unaligned((const u16 *)
+                (dmi_data + DMI_PROCESSOR_MAX_SPEED));
+        *mhz = val > *mhz ? val : *mhz;
+    }
