Hi Marcelo,

After merging the kvm tree, today's linux-next build (x86_64 allmodconfig)
produced this warning:

In file included from arch/x86/kvm/mmu.c:3482:0:
arch/x86/kvm/paging_tmpl.h: In function 'paging64_walk_addr_generic':
arch/x86/kvm/paging_tmpl.h:154:57: warning: unused variable 'shift' [-Wunused-variable]

Introduced by commit 908e7d7999bc ("KVM: MMU: simplify folding of dirty
bit into accessed_dirty").

This reproduces with the version of sphinx in

simply this, for which I will send a patch:
