No technical reason.  It's just that all of the functions in the s390
lowlevellock.h do the syscall directly, so I wrote it that way to
maintain uniformity.  Most (all?) of the lll_futex_* functions could
probably be rewritten as INTERNAL_SYSCALLs and moved into a common
header as a future cleanup.
