This was changed to 'unsigned long' when the thread_info*.h for i386 and x86_64 were merged. Change it back. We can do this as only 27 bits of 'flags' are actually used. This change actually packs down thread_info by 64 bits: 32 bits are saved by the smaller flags, and 32 bits are saved by the following 'mm_segment_t field' becoming naturally 64-bit aligned.
