Waiman Long dfb36e4a8d futex: Use user_write_access_begin/_end() in futex_put_value() ... Commit cec199c5e3 ("futex: Implement FUTEX2_NUMA") introduced the futex_put_value() helper to write a value to the given user address. However, it uses user_read_access_begin() before the write. For architectures that differentiate between read and write accesses, like PowerPC, futex_put_value() fails with -EFAULT. Fix that by using the user_write_access_begin/user_write_access_end() pair instead.
