Do you know if struct switch_stack or pt_regs is ever exposeed to usespace? They are both defined in arch/alpha/include/uapi/asm/ptrace.h which makes me think userspace must see those definitions somewhere.
They are exposed, but why mess with those in the first place? thread_info->status is strictly thread-synchronous, so just use it and be done with that...
