microblaze: Fix __futex_atomic_op macro register usage Old Microblaze toolchain supported "b" contstrains for all register but it always points to general purpose reg. New Microblaze toolchain is more strict in this and general purpose register should be used there "r". Signed-off-by: Michal Simek <monstr@monstr.eu>

futex: Sanitize futex ops argument types Change futex_atomic_op_inuser and futex_atomic_cmpxchg_inatomic prototypes to use u32 types for the futex as this is the data type the futex core code uses all over the place.

futex: Sanitize cmpxchg_futex_value_locked API The cmpxchg_futex_value_locked API was funny in that it returned either the original, user-exposed futex value OR an error code such as -EFAULT. This was confusing at best, and could be a source of livelocks in places that retry the cmpxchg_futex_value_locked after trying to fix the issue by running fault_in_user_writeable(). This change makes the cmpxchg_futex_value_locked API more similar to the get_futex_value_locked one, returning an error code and updating the original value through a reference argument.

microblaze: Futex support Microblaze v7.20 provides new lwx, swx instructions which bring possibility to implement lock rutines. There are some tests in open posix thread LTP part but current toolchain not support it. Signed-off-by: Michal Simek <monstr@monstr.eu>
