irq: use GFP_KERNEL for action allocation in request_irq()
request_irq() calls into proc code via __setup_irq() which is not safe in an atomic context, so request_irq() can itself use the more reliable GFP_KERNEL allocation for the action descriptor. Signed-off-by: Johannes Weiner <hannes@cmpxchg.org> Signed-off-by: Ingo Molnar <mingo@elte.hu>
