+Subject: [PATCH 104/194] ARM: Activate FIQs to avoid __irq_startup warnings
+
+There is a new test in __irq_startup that the IRQ is activated, which
+hasn't been the case for FIQs since they bypass some of the usual setup.
+
+Augment enable_fiq to include a call to irq_activate to avoid the
+warning.
