Michael Brown fdb983d473 Preserve the whole of %esp across prot_call(). We have to split this ... between the low half stored in the static variable rm_sp, and the high half stored on the prot_call() stack, because: Just using the stack would screw up when a prot_call()ed routine executes a real_call(); it would have no way to find the current top of the RM stack. Extending rm_sp to rm_esp would not be safe, because the guarantee that rm_sp must return to the correct value by the time an external real-mode call returns applies only to %sp, not to %esp.		2006-05-06 19:44:23 +00:00
