Detailed Description

A full register dump.

This data structure is created by the instructions

   pushfl
   pushal
   pushw %gs ; pushw %fs ; pushw %es ; pushw %ds ; pushw %ss ; pushw %cs

and can be read back using the instructions

   addw $4, %sp ; popw %ds ; popw %es ; popw %fs ; popw %gs
   popal
   popfl

prot_call() and kir_call() create this data structure on the stack and pass in a pointer to this structure.
