The tip/master's head just a few days ago was 195df42eb64dcb "Merge 
branch into tip/master: 'x86/platform'" and did have dcf67f724b8ada 
"x86/cpu, kvm: Add the NO_NESTED_DATA_BP feature"  but now tip/master 
does not have it -  8272720be044 "Merge x86/cache into tip/master". /me 
confused. What tree is the tree?
