The Linux kernel has a unified process/thread concept so there isn't
really a 'thread data structure' in the kernel. See linux/sched.h
for details.
For userspace stack this is handle by glibc/linuxthreads. On i686
it uses sys_modify_ldt to get per-thread segments, not sure how it
is handled on older CPUs / other architectures.
