51 * We make fsbase and gsbase part of the lwp context (since they're
52 * the only way to access the full 64-bit address range via the segment
53 * registers) and thus belong here too. However we treat them as
54 * read-only; if %fs or %gs are updated, the results of the descriptor
55 * table lookup that those updates implicitly cause will be reflected
56 * in the corresponding fsbase and/or gsbase values the next time the
57 * context can be inspected. However it is NOT possible to override
58 * the fsbase/gsbase settings via this interface.
59 *
60 * Direct modification of the base registers (thus overriding the
61 * descriptor table base address) can be achieved with _lwp_setprivate.
