  47  * We make fsbase and gsbase part of the lwp context (since they're
  48  * the only way to access the full 64-bit address range via the segment
  49  * registers) and thus belong here too.  However we treat them as
  50  * read-only; if %fs or %gs are updated, the results of the descriptor
  51  * table lookup that those updates implicitly cause will be reflected
  52  * in the corresponding fsbase and/or gsbase values the next time the
  53  * context can be inspected.  However it is NOT possible to override
  54  * the fsbase/gsbase settings via this interface.
  55  *
  56  * Direct modification of the base registers (thus overriding the
  57  * descriptor table base address) can be achieved with _lwp_setprivate.
