Viresh Kumar c2775ae4d9 xen: privcmd: Switch from mutex to spinlock for irqfds ... [ Upstream commit 1c68259309 ] irqfd_wakeup() gets EPOLLHUP, when it is called by eventfd_release() by way of wake_up_poll(&ctx->wqh, EPOLLHUP), which gets called under spin_lock_irqsave(). We can't use a mutex here as it will lead to a deadlock. Fix it by switching over to a spin lock.
