http://perforce.freebsd.org/chv.cgi?CH=41554 Change 41554 by peter@peter_daintree on 2003/11/05 20:18:27 note that the gdt allocation still needs to be resolved. The tss needs to be per-cpu still. note to self: ltr appears to load the address of the tss into the hidden tss register. we may not need a per-cpu gdt just to load a tss.
