[PATCH] i386: i386 separate hardware-defined TSS from Linux additions

Not sure about this, now I've done it. Running it here.
If you like it, I can do x86-64 as well.

lguest defines its own TSS struct because the "struct tss_struct"
contains linux-specific additions. Andi asked me to split the struct
in processor.h.
Unfortunately it makes usage a little awkward.
