 *joel* (on branch rtems-4-10-branch):
2011-07-13	Sebastian Huber <sebastian.huber at embedded-brains.de>

	PR 1832/libcpu
	* at91rm9200/irq/irq.c: he bsp_interrupt_dispatch routine does not
	determine the correct interrupt source number. According to the
	datasheet, the reading of the interrupt vector register (AIC_IVR)
	notifies the hardware that the OS is taken care of the interrupt.
	Only after AIC_IVR have been read can the correct source number be
	read from the interrupt status register (AIC_ISR).
