* oskit/x86/main.c (main): BASE_TSS -> KERNEL_TSS
* i386/i386/mp_desc.c (mp_desc_load): Likewise.
Remove magic %gs:0 pseudo-register support.
* i386/i386/ldt.h (USER_GS): Macro removed.
* i386/i386/pcb.c (pcb_init): Set gs to USER_DS, not USER_GS.
(thread_setstatus): Likewise.
* i386/i386/mp_desc.h (struct mp_desc_table): Remove member
`user_thread_register'.
* i386/i386/thread.h (struct i386_machine_state): Likewise.
* i386/i386/mp_desc.c (mp_desc_init): Don't set up USER_GS in LDT.
* i386/i386/ldt.c (ldt_init): Likewise.
* i386/intel/pmap.c (pmap_bootstrap): Don't give users access to
