commit ed5aacc81cd41efc4d561e14af408d1003f7b855 upstream.
XTENSA should only select HAVE_FUTEX_CMPXCHG when FUTEX is
set/enabled. This prevents a kconfig warning.
WARNING: unmet direct dependencies detected for HAVE_FUTEX_CMPXCHG
Depends on [n]: FUTEX [=n]
Selected by [y]:
- XTENSA [=y] && !MMU [=n]
