	* irq/irq.c: Code outside of cpukit should use the public API for
	rtems_interrupt_disable/rtems_interrupt_enable. By bypassing the
	public API and directly accessing _CPU_ISR_Disable and
	_CPU_ISR_Enable, they were bypassing the compiler memory barrier
	directive which could lead to problems. This patch also changes the
	type of the variable passed into these routines and addresses minor
	style issues.

PR 1257/bsps
* irq/irq.c: Code outside of cpukit should use the public API for
rtems_interrupt_disable/rtems_interrupt_enable. By bypassing the
public API and directly accessing _CPU_ISR_Disable and
_CPU_ISR_Enable, they were bypassing the compiler memory barrier
directive which could lead to problems. This patch also changes the
type of the variable passed into these routines and addresses minor
style issues.
