Changeset f278329 in rtems for c/src/lib/libbsp/powerpc

2007-12-01 Till Straumann <strauman@…>

• 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.
