#     powerpc/kconfig: Select HAVE_FUTEX_CMPXCHG
#     
#     The futex code allows architectures to determine at runtime if they
#     support futex_atomic_cmpxchg_inatomic(). It does this by calling that
#     function early in boot and checking if it returns -ENOSYS.
#     
#     That is fine but unnecessary on powerpc, as we always have support for
#     futex_atomic_cmpxchg_inatomic() if the kernel is built with FUTEX
#     support. It also means the first page fault we take at boot is on a
#     deliberate NULL pointer in kernel space, which can be confusing if
#     you're debugging the page fault code.
#     
#     We can avoid the runtime check by selecting HAVE_FUTEX_CMPXCHG, so
#     let's do that.
