+Subject: arm64: Tell irq work about self IPI support
+
+From: Frederic Weisbecker <fweisbec@gmail.com>
+
+commit 3631073659d0aafeaa52227bb61a100efaf901dc upstream.
+
+ARM64 irq work self-IPI support depends on __smp_cross_call to point to
+some relevant IRQ controller operations. This information should be
+available after the call to init_IRQ().
+
+Lets implement arch_irq_work_has_interrupt() accordingly.
