git's rename detection snips away this gem:

+#define HV_LINUX_GUEST_ID_LO		0x00000000
+#define HV_LINUX_GUEST_ID_HI		0xB16B00B5
+#define HV_LINUX_GUEST_ID		(((u64)HV_LINUX_GUEST_ID_HI << 32) | \
+					   HV_LINUX_GUEST_ID_LO)

Somone was trying to be funny, I guess.

KY, I suppose you have access to Hyper-V code or can ask someone who does.
Is this signature actually used in the Hyper-V host code?
