	* rtems/score/cpu.h: Add a per cpu data structure which contains the
	information required by RTEMS for each CPU core. This encapsulates
	information such as thread executing, heir, idle and dispatch needed.

* On some CPUs, RTEMS supports a software managed interrupt stack.

* is performed in _ISR_Handler. These variables contain pointers
* to the lowest and highest addresses in the chunk of memory allocated
* for the interrupt stack. Since it is unknown whether the stack
* grows up or down (in general), this give the CPU dependent
* code the option of picking the version it wants to use.
