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