KVM: x86/mmu: Rename "nxe" role bit to "efer_nx" for macro shenanigans Rename "nxe" to "efer_nx" so that future macro magic can use the pattern <reg>_<bit> for all CR0, CR4, and EFER bits that included in the role. Using "efer_nx" also makes it clear that the role bit reflects EFER.NX, not the NX bit in the corresponding PTE.

tools lib traceevent: Rename input arguments of libtraceevent APIs from pevent to tep Input arguments of libtraceevent APIs are renamed from "struct tep_handle *pevent" to "struct tep_handle *tep". This makes the API consistent with the chosen naming convention: tep (trace event parser), instead of the old pevent.
