ARM and Fast Interrupts

- Subject: 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!
