* shared/irq/openpic_i8259_irq.c:
- conditionally define 'irq_mask_or_tbl' only if
BSP_PCI_ISA_BRIDGE_IRQ is defined.
- use _ISR_Get_level() / _ISR_Set_level() for re-enabling
interrupts rather than messing with MSR directly;
these macros:
o implement compiler memory barrier
o will handle multiple levels (e500 'critical' interrupts)
if they are ever supported.
- decrementer irqs are also shareable - added list traversal.
