ia64: boolean __test_and_clear_bit
__test_and_clear_bit() returns a bitfield with the tested-for bit set. Make it consistent with the other bitops - of ia64 but also every other architecture - and return a boolean value. Signed-off-by: Johannes Weiner <hannes@cmpxchg.org> Acked-by: Fenghua Yu <fenghua.yu@intel.com>
