ARM and Fast Interrupts

Hi,

currently fast interrupts (FIQ) are disabled during rtems_interrupt_disable()
and rtems_interrupt_enable().  This makes them pretty useless since all their
benefits are wiped out.  If someone really needs operating system support for
FIQs he can trigger a software interrupt inside the FIQ handler which does this
job.  I want to change the interrupt disable mask such that FIQs are not
disabled during rtems_interrupt_disable() and rtems_interrupt_enable().  Any
objections?

Have a nice day!
