When HAVE_FUTEX_CMPXCHG is enabled, and FUTEX is disabled,
Kbuild gives the following warning:
WARNING: unmet direct dependencies detected for HAVE_FUTEX_CMPXCHG
Depends on [n]: FUTEX [=n]
Selected by [y]:
- XTENSA [=y] && !MMU [=n]
This is because XTENSA selects HAVE_FUTEX_CMPXCHG,
without selecting or depending on FUTEX, despite
HAVE_FUTEX_CMPXCHG depending on FUTEX.
