They're weirdly ordered now.. I think Dmitry's comment was
just about the usage of space/tab such that git would not get
confused. With that fixed, you should be able to get a diff like:

+#define QCOM_SCM_VMID_LPASS		0x16
#define QCOM_SCM_VMID_WLAN_CE		0x19
+#define QCOM_SCM_VMID_CP_SPSS_SP	0x1A
[...]
+#define QCOM_SCM_VMID_CP_CDSP		0x2A
#define QCOM_SCM_VMID_NAV		0x2B
+#define QCOM_SCM_VMID_TVM		0x2D

Still, I really appreciate you providing that information to the kernel!
