Non-threaded processes without TLS leave FS.base zero, which can be conveniently optimized: setting %fs zeros FS.base for fewer cycles than wrmsr. ok kettenis@ Normalize sentinel.

Also, delete two other unused pcb members: pcb_usersp and pcb_flags. (Deleting pcb_usersp also keeps the pcb_savefpu member aligned properly.) Finally, delete the defines for the unimplemented AMD64_{GET,SET}_LDT sysarch() calls. Tested by various with both AMD and Intel chips ok mikeb@
