Subject: [PATCH] KVM: VMX: More brown paper bags! NOM NOM NOM

Add a missing declaration that got dropped between my inline patch[1] and
what actually got posted[2].

In file included from arch/x86/kvm/mmu/mmu.c:4279:
arch/x86/kvm/mmu/paging_tmpl.h: In function ‘ept_walk_addr_generic’:
arch/x86/kvm/mmu/paging_tmpl.h:496:50: error: ‘EPT_VIOLATION_RWX_SHIFT’ undeclared
 (first use in this function); did you mean ‘EPT_VIOLATION_RWX_MASK’?
