It still doesn't compile because X86_VENDOR_INTEL is missing in
include/linux/peci-cpu.h:

We need something like:

diff --git a/include/linux/peci-cpu.h b/include/linux/peci-cpu.h
index 218fc9372..38cb61203 100644
--- a/include/linux/peci-cpu.h
+++ b/include/linux/peci-cpu.h
@@ -6,6 +6,9 @@
 
 #include <linux/types.h>
 
+/* Copied from x86 <asm/processor.h> */
+#define X86_VENDOR_INTEL       0
+
 /* Copied from x86 <asm/cpu_device_id.h> */
 #define VFM_MODEL_BIT  0
 #define VFM_FAMILY_BIT 8
