In the current implementation both SPSR and ELR registers are saved with the callee-saved registers and restored by the context-switch routine. To support nested IRQs we have to save those on the stack when entering and exiting from an ISR. Since the values are now carried on the stack we can now add those to the ESF and the initial stack and take care to restore them for new threads using the new thread wrapper routine.
