We need to use TASK_SIZE because for 64-bit tasks the value of STACK_TOP actually sits in the middle of the address space so we'll get false-negatives. Adjust the TASK_SIZE definition on sparc64 to accomodate this, in the context in which user_addr_max() is used we have the test_thread_flag() definition available but not the one for test_tsk_thread_flag().
