 Let's change the topic for a minute and think about interrupts.
 Say the processor is running in __Kernel Mode__ (Ring 0, CPL=0) and an
 interrupt happens.  What the processor does then is:
+
 - Push SS and ESP to stack
 - Push EFLAGS to stack
 - Push CS and EIP to stack
 - Load CS and EIP from the IDT
+
 and from there the interrupt handling routine takes over.
 
 The interrupt handling routine does its thing and then runs the `IRET`
 instruction. `IRET` makes the processor do the same thing as when an interrupt
 happens, but _backwards_. I.e:

 - Pop CS and EIP from stack
 - Pop EFLAGS from stack
 - Pop SS and ESP from stack

 The common way a function call is handled by a c compiler is this:

 instruction to the stack and jumps to the callee)
 
 The callee does the following:
